Sanfeng Quick Vision Active Image Measuring Machine from Japan

Sanfeng Quick Vision Active Image Measuring Machine from Japan：

The Japanese Sanfeng Quick Vision Active series, as an economical CNC image measuring machine, boasts compact design, compatibility with dual measurement modes, and high-precision imaging capabilities,
Widely adaptable to quality inspection needs in fields such as electronic components, precision molds, and small mechanical parts. This series includes two basic models, QV-L202Z1L-D and QV-L404Z1L-D,
At the same time, the QVT1 series models equipped with trigger probes were derived, and their technical parameters were optimized around core dimensions such as measurement stroke, optical performance, and precision control. The following is a detailed analysis.

1. Core measurement range and load-bearing parameters:
The series models have clear measurement ranges for workpieces of different sizes. The X × Y × Z measurement range of QV-L202Z1L-D is 250 × 200 × 150mm,
When installing Z-objective 1 x objective lens, the effective stroke of Z-axis is adjusted to 118mm; the larger specification QV-L404Z1L-D reaches 400 × 400 × 200mm,
The corresponding Z-axis stroke under the objective lens is 168mm. There is a significant difference in load-bearing capacity between the two, with the former being able to hold a workpiece weighing 10kg on the worktable and the worktable glass size being 311 × 269mm;
The latter's load-bearing capacity has been increased to 20kg, and the size of the workbench glass has been expanded to 466 × 480mm, suitable for larger volume fixtures and workpieces. The overall size of the machine has also been adjusted accordingly. The basic model has an outer shape of 570 × 767 × 1468mm and a weight of 155kg,
The large stroke model measures 776 × 1303 × 1529mm and weighs 324kg, balancing space adaptability and load-bearing requirements.

2. Optical imaging and illumination system parameters:
This series focuses on precise imaging and flexible observation in optical configuration. Equipped with a high-resolution CMOS color camera and an 8-level zoom optical system,
Under standard configuration, it can achieve a magnification of 0.5-7 times. When paired with optional 1 × or 2 × objective lenses, it can achieve a super long working distance of 74mm with a 1 × objective lens,
The magnification range can be expanded to 1-7 times through a 2xobjective lens, and the total magnification can be increased to 14 times after replacing the objective lens. The optical conditions for ensuring accuracy are set to Z-objective 1.5 x with a zoom magnification of 5.25 x,
Based on this, ensure the consistency of measurement data. The lighting system adopts a multi-dimensional fill light design, including white LED vertical reflection lighting and transmission lighting, and is equipped with 4-quadrant fixed white LED ring lighting,
The angle of light can be adjusted according to the reflective characteristics and contour features of the workpiece surface to avoid shadow interference and ensure clear imaging of edge contours.

3. High precision measurement and positioning parameters:
The measurement accuracy of the series models has reached the level of economical equipment in the industry, with the E1 index of X and Y axis image measurement accuracy being (2+3L/1000) μ m,
The precision of Z-axis E1 is (3+5L/1000) μ m, and the comprehensive precision E2 is (2.5+4L/1000) μ m (L is the measured length). Models equipped with trigger type probes,
X. The measurement accuracy of the Y and Z axes has been further optimized to (2.4+3L/1000) μ m, achieving precision synergy between non-contact and contact measurements. The device uses a linear encoder as the length reference,
The measurement resolution reaches 0.1 μ m uniformly, ensuring precise capture of small size changes. In addition, the high-speed autofocus function can quickly lock the measurement target, and the automatic edge detection technology reduces measurement errors caused by human operation, improving the data repeatability of batch detection.

4. Auxiliary functions and adaptability parameters:
In terms of operation and adaptability, this series is equipped with multiple practical parameter configurations. There are two standards for temperature adaptation, with a reference accuracy of 20 ± 1 ℃,
Simultaneously compatible with conventional workshop environments of 18-23 ℃. Lighting and probe related parameters support flexible adjustment to meet the requirements of different materials of workpieces,
For example, flexible switching of contact probes can be used to avoid surface damage in soft materials. At the software level, it is equipped with QV PAK 3D visual processing software and has pattern search capabilities
With functions such as step-by-step repeated measurement, a single program can complete continuous detection of multiple workpieces. The model also supports the installation of trigger type probes for functional upgrades in the later stage, and reserves a manual temperature compensation function interface.
In terms of power supply and working environment, the equipment is compatible with conventional industrial power sources, and with stable optical and mechanical structures, it can operate stably in ordinary workshop environments without the need for special constant temperature and humidity modifications, greatly reducing the threshold for use.
