Parts of Printing Solder Paste Onto PCB's - Mesh Screen and Metal Stencil Description:
1. Scraper system
* the arch bridge is suspended straight and straight
* programmable suspension self-adjusting stepping motor drives the
printing head
* four-wheel positioning sliding rail structure of bilateral
double-slide block ensures the accuracy and smoothness of operation
before and after scraping
* for before and after the squeegee pressure difference required
and the stability of the lifting design, to prevent leakage of
solder paste and blade clamping design has certain elasticity,
squeegee pressure, lifting speed, the printing speed, print scope
software is adjustable, and provides customers with a variety of
tin under the demoulding ways to adapt to different requirements of
PCB, for the customer provides a good platform for the control of
printing;
* slide rail scraper system to improve operation stability and
prolong service life;
Full closed-loop scraper pressure feedback device, always monitor
the pressure of scraper pressure, make the lower tin more full.
2. Steel mesh positioning system
The size of steel mesh has good and wide applicability
The imported SMC cylinder is used as the cylinder.
Embedded scale, never fall off
Segmented fixed steel frame.
3. Image and optical path system
X, the Y-axis USES the Japanese black field high ground wire rod,
the two ends Japan matsushita motor drive
Internal increase polaroid, automatic accurate grasping different
type of the MARK point
Upper, lower and coaxial 3 uniform light source
Japan's Toshiba industrial camera.
4. PCB transportation and positioning system
The inlet direction arbitrary selection, free combination
Special process of inner tooth transport belt, prevent card board
Programmable transport speed control can make the suspension more
accurate
Use the sexual side clamp and vacuum suction chamber, effectively
clamping the PCB to ensure the complete smooth contact between PCB
and steel mesh.
5. Cleaning system
Spray type cleaning
Dry, wet, vacuum-free combination
Separate cleaning structures
Circular cleaning rubber strip
Cleaning fluid, and steel net cleaning paper amount controlled.
6. Platform calibration system
UVW platform structure, high precision, large rigidity and compact
structure
Triaxial linkage, small volume, high precision
