How to choose a vision dispensing machine: granite, inline, or desktop?

when buying a vision dispensing machine, many purchasers' first reaction is to look at travel and price. But three devices with the same travel can differ by several levels in actual precision and capacity due to different bases and production-line forms. There are three structural divisions: granite, in-line, desktop. Below clearly explains how to choose.

1. First Look at the Workpiece and Production-Line Environment

The first step in selection is not comparing parameters but defining the scenario: what precision level does the workpiece require? Does the product operate alone or integrate into the production line? Is the site and batch R&D sampling, small-batch multi-variant, or large-batch continuous production? These three questions basically push it toward one of three categories. Bolli has corresponding machine models for all three; the key is to define the structure first.

II. Granite vision dispensing machine: the stable reference for precision devices

The granite base resists vibration and has low thermal deformation, and with Vision can push precision very high. Per Bolli data, granite panoramic BL-QB931 is ±0.05mm, BL-QA641 is ±0.15mm; adding granite local Vision, BL-QA531 reaches ±0.02mm. It suits manual module, chip packaging and other precision workpieces. BL-QB931 travel 900×300×100mm, with Hikvision 20MP camera, actual dispensing about 450×300mm, suitable for long-strip precision parts.

III. In-line vision dispensing machine: batch production connecting to the production line

In-line means embedding the vision dispensing machine into the production line, running continuously with upstream and downstream stations. The precision caliber is "in-line panoramic": Bolli BL-SQ431 in-line panoramic ±0.3mm, actual dispensing panoramic about 240×240mm, following about 260×260mm, equipped with Hikvision 1200W camera, reference price about 43,800 yuan. The advantage is non-stop, relying on the panoramic camera to prevent missed points, suitable for mass production. The cost is slightly lower flexibility: after changing products or stopping the machine, recalibration and needle alignment are needed; it is recommended to run through with a desktop machine first.

IV. Desktop vision dispensing machine: a flexible station for R&D sampling and small batches

Desktop vision dispensing machine is the lightest: placed on a workbench, small footprint, portable. Bolli BL-SS331 travel 300×300×100mm, equipped with Hikvision 500W camera, following precision ±0.5mm, actual dispensing about 260×260mm, reference price about 38,800 yuan; larger BL-SS441 travel 400×400×100mm, equipped with Hikvision 1200W camera, actual dispensing about 360×360mm, about 43,800 yuan. Screw plus servo covers most general dispensing sufficiently, especially suitable for R&D sampling and frequently changed small-batch multi-variety.

5. Three Steps to Set the Plan: Sample First, Then Decide

after the structure is set, implementation is divided into three steps: first confirm workpiece size and precision grade; then select the machine model by whether to go on the production line and batch; finally use Bolli's unlimited free sample testing to verify the glue path, yield, and takt before purchasing. Bolli vision dispensing machine uniformly equips Hikvision camera, self-developed light source, Leadshine servo, and Xinsheng screw; after-sales provides unlimited remote assistance, so you neither waste money nor rework due to insufficient precision or takt.

The core of the dispensing machine coordinate system is distinguishing machine coordinates from workpiece coordinates. Machine coordinates use the mechanical origin as the absolute reference of the equipment; workpiece coordinates use the product as reference so programming coordinates match drawing dimensions. The two are linked by origin offset — resetting the workpiece origin handles product changes. Z-height compensation copes with different product thicknesses, and vision coordinate mapping ties camera to motion through calibration.

vision dispensing machines are divided into three types by structure: granite, in-line, desktop — granite has the highest precision, suitable for precision devices; in-line connects to the production line, suitable for large-batch continuous production; desktop is flexible, suitable for R&D sampling and small-batch multi-variety. First determine the structure by workpiece precision, whether to go on the production line, and batch, then decide after verification with Bolli's free sample testing.
