Valve Stem Automatic Visual Counting and Packaging Machine

Ningbo Langs Industrial Co., Ltd. has been deeply involved in the field of machine vision inspection for 16 years. As a professional high-tech enterprise, our inspection covers a wide range of materials, including rubber and plastics, precision hardware, stamping parts, various materials, and ceramics. We have launched a CCD valve stem automatic visual counting and packaging machine with an automatic feeding mechanism equipped with sensors. The machine can intelligently organize products to be inspected and visually classify and package valve stems that meet the requirements.

Product Description

Valve stem automatic visual counting and packaging machine is an automated device independently developed by our company for inspecting the appearance and structural dimensions of products. Automatic visual counting and packaging machines adopts a PLC control system and the vision inspection system. Materials transported by a high-speed vibrating feeder are conveyed through a high-transmittance glass disk to the designated camera's field of view. Finally, a solenoid valve blows air to accurately classify defective and good products.

Q&A

Q1 :What is the resolution of valve stem automatic visual counting and packaging machine?‌

A:The resolution ranges from hundreds of thousands to hundreds of millions of pixels. For example, a 5-megapixel camera achieves a theoretical resolution of 0.02mm under a 100mm field of view.

Q2 :How do valve stem automatic visual counting and packaging machine handle high-speed production?‌

A:High-frame-rate cameras, hardware acceleration (e.g., GPU/FPGA), optimized algorithms, and synchronized triggering mechanisms ensure image acquisition and processing without stopping the production line.

Q3 :What is the impact of environmental factors on visual counting and packaging machine?‌

A:Temperature changes cause thermal expansion and contraction affecting precision; dust contaminates the lens; vibration causes image blur; strong light interferes with imaging. Protective covers, temperature control, and vibration damping measures are required to mitigate these issues.

Q4:How do visual counting and packaging machine handle vibration and movement?‌

A:Short exposure time freezes motion, encoder synchronized triggering, image stabilization algorithms, or detection at a stationary workstation (e.g., turntable) are used.
