The core of robot vision dispensing in automotive manufacturing is to achieve high-precision and consistent sealing, bonding, and potting operations through visual positioning and automatic dispensing, covering the entire process of vehicle body, electronics, power, interior and exterior decoration, greatly improving assembly quality and efficiency. The following are specific application scenarios:
1、 Vehicle body manufacturing and sealing
1. Sealing of body welds
Apply sealant/glue to the welds of the vehicle's bottom panel, side panels, roof, etc. The vision system correctly identifies the trajectory of the welds, and the robot evenly applies glue along the welds to achieve waterproofing, rust prevention, and sound insulation, replacing manual glue application and avoiding missed or broken glue, thus improving the sealing performance of the vehicle.
2. Door/hood/trunk sealing
Automatically apply sealant or damping glue on the sheet metal edges of the car doors, engine hood, and trunk lid, visually locate the contour, ensure uniform and continuous glue lines, achieve waterproof, dustproof, shock absorption, and improve assembly accuracy.
3. Adhesive bonding of vehicle body structure
Perform structural adhesive bonding on aluminum/steel components and carbon fiber components of the vehicle body (such as door inner and outer panels, roof and body), visually guide robots to correctly apply adhesive to ensure bonding strength, replace partial welding, and achieve lightweight vehicle body.
2、 Automotive Electronics and Electrical Systems
1. Encapsulation and sealing of electronic controllers
Apply sealing adhesive to electronic controllers such as ECU (engine control unit), BCM (body control module), sensors, etc., visually locate the sealing area, and correctly inject epoxy resin, polyurethane and other sealing adhesives to achieve waterproof, dustproof, shockproof, insulation, and protect internal circuits.
2. Wiring harness and connector sealing
Apply sealant and hot melt adhesive to the wire harness joints, connector terminals, and wire harness branches, visually identify the position of the terminals, seal them correctly, prevent water vapor and dust from entering, avoid circuit short circuits, and improve the reliability of the electrical system.
Sealing and bonding of power batteries
3. New energy vehicle power battery pack:
Sealing of battery pack shell welds and flange surfaces, visual guidance with adhesive coating, achieving IP67/IP68 waterproof rating;
Structural bonding between battery cells and modules, module and casing, dispensing of thermal conductive adhesive, visual positioning of battery cell gaps, correct application of thermal conductive adhesive, improving heat dissipation and structural stability.
4. Sealing and bonding of car lights
The lampshades and shells of car headlights and taillights are bonded and sealed, visually identifying the contours. Polyurethane sealant is applied to ensure waterproofing and dust prevention, while improving the assembly accuracy of the headlights to avoid light leakage and water ingress.
3、 Powertrain and chassis system
1. Engine/transmission seal
The joint surfaces of the engine cylinder head, oil pan, and gearbox housing are sealed, and the trajectory of the joint surface is visually located. The sealant is automatically applied to replace manual labor, ensuring uniform sealing, preventing oil and gas leakage, and improving the sealing performance of the powertrain.
2. Bonding and damping of chassis components
The structural bonding of chassis suspension components and subframe, as well as the application of damping adhesive to chassis sheet metal parts, provide visual guidance for correct operation, enhance the strength of chassis structure, and reduce driving noise and vibration.
4、 Interior and exterior decoration assembly
1. Adhesive bonding of interior parts
Adhesive fixation of interior components such as dashboard, center console, door panels, and ceiling (such as interior panels and sheet metal, decorative strips and substrates), visual positioning of adhesive positions, application of hot melt adhesive and structural adhesive to ensure firm adhesion and improve interior assembly accuracy and aesthetics.
2. Bonding of exterior components
Adhesive installation of exterior parts such as logos, decorative strips, spoilers, radar brackets, etc., visual recognition of installation positions, correct glue application, replacing buckles/welding, avoiding damage to the vehicle body, and improving the consistency of exterior assembly.
3. Glass bonding
Polyurethane structural adhesive bonding for the front windshield, side windows, and sunroof. The vision system locates the glass and body mounting holes/contours in real-time, and the robot applies adhesive correctly along the edge of the glass to ensure the strength and sealing of the glass bonding, achieving automated assembly.
5、 Core advantages
High precision: The visual positioning accuracy can reach ± 0.05mm, suitable for complex contours of automotive components, avoiding glue line deviation and missed coating.
High consistency: The glue quantity, glue diameter, and glue line trajectory are correct and controllable, ensuring uniform assembly quality for each vehicle and reducing the rate of defective products.
Flexibility: By visually recognizing different vehicle components, quickly switching programs, and adapting to multi vehicle co production.
High reliability: reduces manual operation errors, improves sealing, bonding, and potting quality, and reduces after-sales failure rates.
