In the production process, it is crucial for enterprises to strictly control the impact of each production link on product quality. Before the operation of a fully automatic precision dispenser, various confirmation tasks must also be completed. First, adjust the distance between the dispenser's needle and the product according to specific conditions, then expel the air from the needle, and verify whether the glue volume for each product is within the specified range. Each type of dispenser has its own advantages. The main preparation and handling procedures for a fully automatic precision dispenser before dispensing mainly include several basic steps: glue delivery confirmation, glue valve testing, air bubble removal, and glue test dispensing. The preparatory work before dispensing plays an important supporting role in the subsequent formal encapsulation.
After the glue valve test is completed, it is necessary to deliver glue to the dispenser and glue filling machine. At this time, constant attention must be paid to whether air bubbles are generated in the glue. For existing air bubbles, identify which cylinder they are generated in, then apply pressure to that specific cylinder to remove the bubbles. If the glue fails to flow normally after pressure application, it is highly likely that the interior of the glue valve is blocked, and the glue valve needs to be cleaned at this point.
The primary procedure in the preparatory work before the encapsulation operation of dispensers and glue filling machines is: after filling the glue into the glue cartridge, the amount and viscosity of the filled glue must be compared with the preset values. Only after confirming that there are no discrepancies can the subsequent glue valve testing work be carried out. The glue valve test mainly refers to testing the integrity of the glue valve. The glue valve is a device that controls a series of variables such as fluid volume. The precision and quality of the glue valve directly affect the dispensing quality, so it is particularly important.
