source：8678g.com | Release time：2026年05月18日1、 New energy vehicle three electric system (core scenario)
1. Battery Pack Glue Filling and Sealing
Box sealing: Apply polyurethane/epoxy sealant between the upper and lower covers, with IP67 protection, preventing water ingress and salt spray.
Heat conduction encapsulation of module: heat conduction epoxy/silicon gel is injected between the electric core and the shell to dissipate heat+insulate+shock, improving thermal stability.
Wire harness/connector encapsulation: waterproof insulation, high-voltage safety enhancement.
2. Electric drive/electronic control unit (MCU/OBC)
Shell sealing: The flange surface is coated with glue for dust and water resistance.
Power module encapsulation: IGBT/capacitor epoxy encapsulation, heat dissipation, insulation, and vibration resistance.
Three anti coating for control board: normal coating, moisture-proof and corrosion-resistant.
3. Charging stations/high-voltage components
Module encapsulation, terminal sealing, and shell bonding ensure high voltage insulation and outdoor durability.
2、 Assembly of body and white body seal
1. Car door/rear cover/engine hood
Folding glue: Apply PVC/epoxy glue at the folding edge of the inner and outer panels to enhance rigidity, waterproof and rust proof.
Glass adhesive: Apply polyurethane adhesive to the car window/sunroof glass and body, bonding+sealing+shock absorption.
2. Body welds/flooring/door sills
Weld seam sealant: Apply sealant at the weld seam to prevent rust and water.
Floor damping adhesive: shock-absorbing and noise reducing, enhancing NVH.
Threshold/pillar reinforcement: structural adhesive+foam adhesive to enhance collision safety.
3. Sunroof/roof/rearview mirror
Assembly of sunroof frame with adhesive coating, roof bonding, sealing of rearview mirror base, 3D visual tracking of complex surfaces, and even adhesive application.
3、 Automotive Electronics and ADAS Precision Assembly
1. Domain controller/ECU
Shell sealing+PCB encapsulation: epoxy/silicone protective components, resistant to vibration and temperature changes.
Adhesive dispensing for connectors: Strengthen and prevent loosening, improve reliability.
2. Lidar/camera
The lens is sealed with the housing, and the internal components are sealed to prevent dust and water, ensuring stable imaging.
3. Sensors/Millimeter Wave Radar
Glue protection+structural bonding, suitable for high temperature and vibration conditions.
4、 Interior and exterior decorations, as well as other components
Car lights: The lampshade and base are sealed with hot melt/epoxy adhesive to prevent water ingress and fogging.
Instrument panel/central control screen: border bonding, backlight module encapsulation, shockproof and anti glare.
Battery cooling plate: bonded with thermal conductive adhesive to improve heat transfer efficiency.
Seat/Interior Decoration: Structural adhesive bonding, foam filling, lightweight+noise reduction.
5、 Core Value (Why Use Robot Line)
Stable accuracy: Repeat positioning ± 0.02mm, glue amount error ≤ ± 2%, to prevent glue breakage/overflow.
Efficiency leap: The single door takes about 1 minute, the battery pack is 60JPH, and the production capacity is increased by 3-5 times.
Reliable quality: IP67 compliance rate of 99.8%, vibration resistance increased by 40%, reducing after-sales risks.
Flexible hybrid line: 3D vision automatically adapts to multiple vehicle models, with fast changeover.
Data traceability: MES linkage, full process recording of trajectory/adhesive amount/pressure, meeting compliance requirements.
6、 Typical process flow (taking battery pack as an example)
Loading positioning → 3D vision scanning → robot applying sealant (lower box) → module entering box → robot filling thermal conductive adhesive → upper cover coating → compression tightening → curing → inspection → unloading.
