How to apply 3D vision to the design of automobile chassis

The automobile chassis is the basic structure of the automobile, which plays multiple roles, including bearing, supporting, transmitting power, and eliminating vibration . It is mainly composed of the transmission system, driving system, steering system, braking system , etc. The chassis assembly has a wide variety of parts, complex processes, and high quality standards , and the production process has generated a large number of automation upgrade requirements.

Mecha-Mind Works with integrator partners to enable the manufacturing of many er1 and large automotive parts , using +3D vision technology to achieve chassis componentization and flexible production . Intelligent robot workstations work with CNC, welding systems, measurement systems, etc. to help end customers substantially improve production line production efficiency and quality standards .

Drivetrain

3D vision guides shell grabbing and loading

Application Background:

The gearbox housing has a reflective surface and a complex structure; it is heavy, has a long processing flow, and requires a lot of manual loading.

Machining is required, and high precision is required for grabbing and placing.

Application advantages:

The structured light industrial 3D camera Mech-Eye PRO S scans and images the reflective and complex structured gearbox housing, quickly and accurately generating high-quality 3D point cloud data .

Arm-mounted installation allows for high-precision positioning of the gearbox housing one by one, guiding the completion of latch grabbing.

Quickly identify the gearbox housing and distinguish the front and back , guiding the robot to grasp it.

Mech-Vision can be used to complete one-stop deployment of 3D vision applications, quickly increase production and change production to meet flexible production needs.

3D vision guides the sub-axis to grab and load materials

Application Background:

The secondary axis is dark and reflective, and fits snugly in the large basket.

The workpiece and the basket are similar in color, which requires high recognition capabilities of the 3D vision system.

Application advantages:

The Mech-Eye LSR L laser 3D camera can generate high-quality point cloud data for dark and reflective secondary axes .

Advanced 3D Vision,

Accurately identify the secondary shaft that fits tightly and is similar in color to the basket

.

The secondary shaft can be dimensioned to ensure that the size can be accurately placed in the fixture during subsequent processing.

Mech-Eye LSR L has high precision, large field of view, and large depth of field . It can still maintain millimeter-level positioning accuracy when installed at a long distance , meeting the production needs on site that require both precision and field of view.

Driving system

3D vision-guided wheel grabbing

Application Background:

The wheel hub is heavy and requires a lot of manual handling.

Grabbing the beat is demanding.

Application advantages:

It can produce high-quality images of wheels with reflective surfaces and complex structures .

It can accurately identify partitions, guide robots to grab them, and improve the automation level of production lines.

The grabbing speed is fast and the rhythm meets the actual production needs.

Mech-Vision built-in Wheel grabbing Typical engineering , users can quickly call and adjust according to actual production conditions.

3D vision guides axle grabbing and loading

Application Background:

The axle is a chassis component of an engineering vehicle. It has a very heavy weight and is difficult to move manually.

Axle surfaces are reflective and covered with oil

.

Application advantages:

It can handle the highly reflective axle , accurately locate it, and guide the robot to complete stable grasping.

It can adapt to workpieces of different specifications, and product types can be quickly increased in the later stage.

No need for precisely positioned material baskets or customized tooling, saving workstation construction costs .

Mech-Vision integrates configuration, camera calibration, workpiece recognition, path planning and other functions, and can complete the one-stop deployment of 3D vision applications with simple operations.

Subframe online measurement

Application Background:

The subframe has a reflective surface and a complex structure.

The workpiece to be measured has a large number of precise measuring points, which places high demands on the measurement system's accuracy, speed, and flexibility .

Application advantages:

The micron-level precision industrial 3D camera Mech-Eye UHP-140 has ultra-high precision and can handle subframes with reflective surfaces and complex structures , generating high-quality 3D point cloud data for various assembly features.

Advanced measurement algorithms enable fast and accurate measurement of key features such as round holes, threaded holes, studs, and waist holes .

Multiple cameras and multiple robots work together to flexibly respond to features in different locations and quickly complete the measurement tasks of large workpieces.

Self-developed measurement software aggregates measurement data in real time to control production quality and optimize front-end processes .

Braking system

3D vision guides the grabbing and loading of brake discs

Application Background:

After fine machining, the brake disc has a high-gloss reflective surface.

The incoming brake discs have inconsistent stack shapes and are stacked in an alternating manner.

Application advantages:

Can handle brake discs with complex surfaces and high gloss reflective surfaces .

The 3D vision system can accurately identify the front and back sides of the brake disc and the partition, making production more flexible.

Easily handle large stacks and large baskets , compatible with various material input methods such as pallets and wire mesh baskets .

The dual cameras correspond to the different specifications of brake discs in the dual stacks, which greatly improves production efficiency.

Mech-Vision built-in brake disc typical project, supports one-click production increase and production change , and simple operation can complete the rapid introduction of new products.

In addition to various chassis parts, Mecha-Mind AI+3D technology is also widely used in the production and quality monitoring of body sub-assemblies and body structural parts , helping automotive industry customers improve production efficiency and product quality. At the same time, Mecha-Mind can provide integrator partners with full-link support in delivery, training, and market , helping integrator partners to quickly and conveniently deliver various complex robot applications to end customers.
