The jetting, belongs to the new led lights technology, which uses a nozzle alternative to syringes, to solve many problems. Jetting nozzles needed to fill the bottom of the device above the dispensing need to reach their location below the top (street solar lighting). Jetting nozzles in the entire circuit board side along the x and y directions, without the need for vertical movement.
And dispensing syringe, the nozzle does not form a continuous bottom-filling glue flow, and replaced every second jet more than 200 points after accurate measurement of the gel-point. With the move of the nozzle level, the gel-point can be the formation of linear and pattern of a variety of needs, the solid line, dotted line and a variety of other different graphics. Each jet by precise control of a jet formed by the gel-point minimum diameter of up to 0.33mm, for coating plastic patch area into the precise control of occasions is very important.
Injection technology is the glue from the nozzle at a faster rate, rely on glue momentum to make glue out of the nozzle. Each jet (street solar lighting) will spray out a certain amount of glue. Common injection frequency is 100 Hz to 200 Hz, but will soon reach 1000hz. , There are several different jet dispensing needle dispensing. When the glue from the nozzle, before the glue in contact with the substrate and the separation nozzle. Each of the gel-point injection into the substrate to form points, lines, and graphics. In the dispensing position during the move, the dispensing head is not the movement of the Z-axis direction, thus saving a considerable amount of time. Needle dispensing robot in the X, Y, Z axis movement, glue flow from the needle out of contact with the substrate, relying on gravity and the substrate surface tension glue isolated from the needles. After the completion of each dispensing, a movement along the Z axis, and then move to the next dispensing position.
The LED products market is also benefiting from the spray adhesive technology. Spray adhesive process can spray a wide range of optical materials including silicone, UV curable conductive adhesive of the phosphorus doped in the high-speed dispensing position and precise dispensing and plastic volume control. The accuracy of the spray adhesive can improve the yield of high-value high-power LED street lights devices. Applied to the white light (street solar lighting) production, phosphor powder and mixed glue dispensing, its consistency is a good improvement.
