Measurement Sensors for the Electric Vehicle Industry

The TM-X5000 Series projects the 2D shape of a web's edge to measure thickness with high accuracy. By capturing the surrounding area, the TM Series can account for web decentering or roll runout to correctly measure the material thickness regardless of surface condition.

Detect chipping or dents in laser welded beads using 3D laser profilers. The measurement is unaffected by color or gloss of the weld, making inspection results stable through glare or bead shape variation.

Measure core eccentricity without touching the part. The high-speed sampling of the LS-9000 Series enables accurate measurement of the core position and diameter during rotation and eliminates operator error.

The LJ-S8000 Series 3D Laser Snapshot Sensor uses a line laser to scan the target surface, inspecting both the height and position of stator terminals at the same time. In addition, the LJ-S8000 Series’ built-in scanner eliminates the need for auxiliary parts, such as stages and encoders, therefore eliminating the time otherwise needed for specifying and implementing those additional devices. Inspections are possible simply by attaching the LJ-S8000 Series to the equipment.

The LJ-S8000 Series 3D Laser Snapshot Sensor can inspect the heat dissipation material applied by a dispenser. Although simultaneous inspection of width and height is difficult with grayscale images from conventional vision sensors, the LJ-S8000 Series scans the target surface shape to obtain height information that can be used for inspecting height, width, and volume of heat dissipation materials. Since the scanner is built into the sensor head itself, no additional resources or time are required for auxiliary parts, such as stages and encoders. Inline inspections with the LJ-S8000 Series are as simple as attaching the device to existing equipment.

Since the battery on an EV is situated under the floor, the battery case must be airtight to prevent water and foreign matter from entering it. The LJ-X8000 Series features a wide dynamic range with high sensitivity, allowing for stable and reliable inspections.

Appearance inspections of targets with variations in surface color or gloss, such as welding beads, are not stable with conventional grayscale images. With 3D appearance inspection, however, height measurement data makes it possible to detect uneven surfaces without being affected by the target surface condition. In addition, the LJ-S8000 Series 3D Laser Snapshot Sensor’s built-in scanner eliminates the need for auxiliary parts such as stages and encoders, and therefore also eliminates the time otherwise needed for specifying and implementing those additional devices. Inspections are possible simply by attaching the LJ-S8000 Series to the equipment.

Measure electrode thickness. To ensure proper coating application, the thickness must be determined accurately. This is achieved by calculating the thickness of the electrode and the foil itself after coating.
The special jig assists in properly aligning the sensor heads, which reduces measurement error and makes it easy to acquire high accuracy measurements.

Inline width measurement of battery parts cut by slitting machines. The dimensions can be managed without being affected by ambient light or electrode tilting during conveyance.

The outer diameter is instantly measured at multiple locations after the cover is staked and bonded to the can. High-speed exposure and a large depth of field of up to ±20 mm ±0.79″ allows for stable inline inspection.

The anode of lithium metal batteries, which are a type of solid-state battery, is formed inside a vacuum chamber. The vacuum- compatible CL-S015 can provide vacuum evaporation conditions and improve yield rates by measuring thickness inside the chamber.

The presence of lamination misalignment is checked after the lamination process. The LJ-X8000 Series can obtain profiles at a minimum pitch of 2.5 µm 0.000098″, ensuring that every electrode profile is accurately measured even during conveyance.

The height inspection of bus bars before welding and the inspection of XY positions after welding can be performed with a single system. Although the inspection of X and Y positions can be performed by conventional vision systems, with the 3D data of the LJ-X8000 Series, XY position as well as Z-height data can be inspected simultaneously.

The TM-X5065 measures the hairpin profile after forming.
The TM-X5000 Series can measure widths, angles, and height differences simultaneously, preventing improper assembly of the stator and improving production yield.
