The desktop dispensing platform has strong adaptability in the optoelectronic industry due to its high precision, small size, and flexible operation. Its core focus is on the dispensing needs of miniaturization, high precision, and high consistency, covering the entire production process of optoelectronic devices (packaging, assembly, die bonding, sealing, etc.). The following are segmented application scenarios+adaptation processes+core requirements, correctly integrating with industry practices:
Core applications of desktop dispensing platform in the optoelectronic industry (fully segmented scenarios)
1、 Core application logic
The desktop dispensing platform (including semi-automatic/fully automatic models) focuses on small stroke (usually 50-300mm), high precision (repeated positioning ± 0.01~0.05mm), and correct glue control (dispensing volume starting from 0.001ml). It is suitable for micro dispensing of small devices (chips, lenses, modules) in the optoelectronic industry, replacing manual labor to improve consistency and avoid overflow and shortage of glue affecting performance. It is an equipment for small and medium-sized production and R&D sampling in the optoelectronic industry.
2、 Segmented application scenarios (benchmarking upon implementation)
Scenario 1: Optical communication devices (core essential, high precision requirements)
Adapter components: fiber optic connectors, optical modules (SFP/QSFP), optical attenuators, couplers, wavelength division multiplexers
Key dispensing processes and applications
Fiber end face fixation/bonding: Epoxy/UV glue is applied at the contact surface between the connector core and the fiber to fix the fiber and ensure stable optical signal transmission. It is required to have no bubbles and a uniform adhesive layer (thickness ≤ 5 μ m)
Optical module packaging and sealing: sealant/thermal conductive adhesive is used to seal the gaps between the module housing and the base, preventing dust and water vapor from entering, while assisting in heat dissipation, and adapting to high-speed optical modules (10G/40G/100G)
Device pin reinforcement: Conductive silver glue is applied at the connection between the metal pins of the optical device and the substrate to reinforce and ensure conductivity, avoiding vibration and detachment
Core requirements of the platform: repeated positioning accuracy of ≤± 0.02mm, support for dispensing/drawing lines/surrounding glue, compatible with UV glue rapid curing linkage
Scenario 2: Display devices (batch adaptation, emphasizing consistency)
Adapter components: Mini/Micro LED, LCD/OLED module, touch screen, backlight module, camera module
Key dispensing processes and applications
Mini/Micro LED Solid Crystal Glue: Solid crystal glue/insulation glue is applied at the corresponding points on the PCB substrate to correctly bond the LED chip. The glue point diameter is ≤ 0.1mm to avoid uneven glue amount causing chip offset (affecting display consistency)
Touch screen bonding and edge sealing: The touch screen glass and touch layer edge points are sealed with waterproof sealant to prevent light leakage and water vapor, and the adhesive line is required to be continuous without breaks
Backlight module bonding: Apply hot melt adhesive/acrylic glue at the connection between the backlight board and the frame, as well as the light guide plate and the light strip, to fix them without affecting the light transmittance
Camera module fixation: lens holder and PCB board point structure adhesive ensure the accuracy of lens stabilization, and the adhesive layer has no shrinkage or deformation

3、 Exclusive adaptation requirements for the optoelectronic industry (must see when selecting equipment)
Accuracy requirements: The core depends on the repeatability positioning accuracy. Optical communication/optical components should be ≤± 0.01~0.02mm, and display/laser devices should be ≤± 0.03~0.05mm
Adhesive type adaptation: It must be compatible with optoelectronic special adhesives (UV adhesive, epoxy adhesive, conductive silver adhesive, thermal conductive adhesive, optical adhesive), supporting low viscosity (≤ 100CPS) to high viscosity (≥ 100000 CPS) adhesive types
Pollution prevention: The countertop needs to be anti-static and dust-proof, with no wire drawing or dripping glue on the adhesive path to avoid contaminating the photoelectric sensitive components
Linkage function: Priority should be given to models with UV curing lamp linkage and temperature control table adaptation, to meet the needs of rapid curing of photoelectric adhesive and temperature control dispensing
Travel adaptation: Choose according to the size of the device. For small devices (chips, lenses), choose a travel of 50-150mm, and for module types, choose a travel of 150-300mm
