Material and Manufacturing Process
Substrate
6061 aluminum alloy turn milling composite CNC integrated molding, natural color machined surface, no surface treatment; The center step coaxial inner hole, four ear flange installation hole, and annular sealing step are clamped in one go, and the coaxiality of the center hole and the flatness accuracy of the flange sealing can reach ± 0.01mm.
Process characteristics
Four sided symmetrical four ear installation convex platform: the four point locking force is evenly distributed, and assembly will not produce deflection stress;
Double layered annular stepped convex platform: the outer layer is a flange sealing surface, and the inner layer is equipped with a high positioning cylinder to form an independent cavity for accommodating optical lenses, micro servo motors, and bearing bushings;
All edges have R-angle transitions to prevent scratches on the sealing ring and outer ring of the lens.
Material advantages
lightweight, excellent thermal conductivity, can quickly export the working heat of the lens and motor; Non magnetic, will not interfere with optical path imaging and micro motor magnetic field.
Structural and functional disassembly
1. Four ear flange locking base
Four sets of countersunk through holes are arranged around the perimeter, and screws are threaded through to lock the entire cover onto the visual shell, hollow positioning base, and angled adapter bracket; Four point uniform compression ensures that the central component does not shift due to long-term vibration.
2. Double layer coaxial stepped center cylinder
Inner through-hole: embedded with industrial lenses, laser collimating lenses, micro servo motors, bearings, and steps to achieve axial limit;
Outer ring sealing platform: It can be embedded with an O-ring to prevent dust and volatile media from entering the chamber, and isolate internal optical/electrical components from adhesive dust pollution in the workshop.
3. Circular buffer step
A small assembly gap is reserved between the high and low steps, and buffer pads can be installed to absorb the impact and vibration caused by the high-speed start stop of the slide table, stabilizing the imaging and dispensing accuracy.
Assembly and positioning of the entire visual dispensing equipment
Belonging to the core compression positioning flange of the visual module, assembly link:
Diagonal valve body adapter bracket/hollow integrated base → Install circular lens positioning flange base → Cover with this four ear pressure cover for locking and fixing → Outer cover with black shading shell
Function: Tighten and fix the internal lens and laser module. The four point flange ensures that the optical path is coaxial throughout the entire process, and the sealing step blocks dust. It is a dust-proof clamping component for the visual positioning unit.
Core application scenarios
Visual glue machine industrial lens compression flange (complete set of parts matching)
Used inside the camera shading housing to press and fix the telecentric/fixed focus lens, with a sealed structure to prevent UV glue from evaporating and fogging the lens in the workshop. Four point locking eliminates assembly stress, avoids imaging distortion, and ensures precise matching between visual coordinates and dispensing nozzles.
Micro servo motor bearing end cover
The motor clamping end cover of the automated fine-tuning shaft system, the central cylinder accommodates the bearing and motor rotor, the flange is locked and fixed, and the aluminum alloy heat dissipation reduces the motor temperature rise, improving the repeatability accuracy of fine-tuning.
Laser detection collimating mirror sealing cover
Built in laser collimating lens, sealed groove connected to dust-proof blowing air path, isolated processing dust pollution light path, stable laser output spot size.
Classification of similar components
• Distinguish three ear lens flange: Three ears are only fixed at three points, with weaker force uniformity than the four ear structure of this component, and are mostly used for small lenses; This four point bearing lens/motor module has a larger size;
• Distinguish fluid valve body flange: The valve body flange has a built-in cross fluid flow channel, and this part only has a central through-hole without a medium delivery channel;
• Difference from simple adapter rings: There are no multi-layer raised step sealing cylinders or flange installation ears around, only a single thin ring, which cannot independently press the sealing module.
