What does a vision dispensing machine mean? What is its working principle?

Many people new to automated production lines find the term ”vision dispensing machine” unfamiliar at first. Simply put, a vision dispensing machine is an automatic dispensing device with an added set of“Vision眼睛”and ”大脑”, allowing the equipment to see the workpiece position by itself, automatically align, and then dispense. It belongs to a class of dispensing equipment with a relatively high degree of automation.

1. What exactly is a vision dispensing machine

conventional dispensing equipment relies onmachine mechanical positioningmagazinemanual alignment, a slightly crooked workpiece can cause off-target dispensing; a vision dispensing machine mounts an industrial camera and Vision software on the machine table — it first photographs, then recognizes the workpiece's position and features, and the control system automatically compensates the deviation. Bolli vision dispensing machine adopts Hikvision cameras with self-developed Vision software, exactly to make the ”see clearly” step stable and reliable.

2. What it relies on to ”see” — Vision positioning

The core of Vision positioning is“Capture—Recognition—Conversion”. The camera photographs the workpiece; the software extracts edges, contours, or feature points to obtain the workpiece's coordinates in the current view; then manual-eye calibration converts image coordinates into machine coordinates, and the dispensing head knows where to move. Bolli vision dispensing machine relies on a self-developed control system to centrally manage camera and light source, so recognition results can directly drive the motion axis.

3. How it ”moves” — motion and dispensing

After the position is clearly seen, the motion system moves the dispensing head to the target point. Bolli vision dispensing machine adoptsLeadshine servo motor plus Xinsheng precision screw-driven platform, working with self-developed control software to plan motion paths; once in position, the dispensing valve opens and closes as set, controlling the dispensing volume and glue-dot size. Compressed air is delivered through the air line; Bolli equipment's air-source pressure typically operates in the 600–1200 hPa range, providing stable power for dispensing and suction.

4. A complete dispensing process

The typical process is:workpiece loading → camera recognition → coordinate transformation and alignment → dispensing along the preset path → workpiece unloading. If a model change is needed midway, simply call the corresponding program in the software without major hardware modification. Bolli vision dispensing machine uses an Intel i7 industrial control machine to handle control and Vision computing, ensuring response speed under multitasking.

5. Why use a vision dispensing machine

When incoming materials have deviations, complex shapes, or require less labor-intensive production, a vision dispensing machine's value is most evident: it tolerates some placement error, reducing defects from misalignment, and frees workers from repetitive alignment. Not all machine models share the same positioning-accuracy spec; for example, Bolli's follow-type equipment is ±0.5 mm and granite-platform panoramic equipment can reach ±0.05 mm — judge by process requirements and actual machine sample testing when purchasing.
