With the advent of current bonding technology, dispensing equipment is indispensable in the bonding process, so the spray dispensing valve is a kind of terminal equipment in the bonding process.
The dispensing valve can precisely control the amount of glue used in the bonding port in precise production. Its operating principle is: transport compressed air into the glue bottle through a special equipment, and use its air pressure in the feed pipe connected to the piston chamber Press the glue in. When the piston moves to the upstroke, the glue will fill the piston chamber, and the glue will be squeezed out of the needle during the downward movement of the piston. Therefore, the distance under the piston determines the amount of glue dripping out, which can be adjusted manually, or it can be controlled by its professional software. The operation is simple and convenient.
However, during operation, the factors that affect the dispensing effect are generally the thickness of the glue, the dispensing pressure, the thickness of the needle, the interval between the needle and the working surface, the viscosity of the glue, the temperature of the glue, the curing temperature curve, and the bubbles in the glue. , Need specially set fluid and so on. The needle of the dispenser should generally be selected with a needle whose inner diameter is about 1/2 of the diameter of the dispensing dot. During the dispensing process, the dispensing needle should be selected according to the size of the product.
The distance between the needle and the working surface, different dispensers use different needles, some needles have a certain degree of stop, so it is necessary to master the dispensing interval, and even the needle and the working surface should be made before each operation is turned on. Interval calibration, that is, Z-axis height calibration, etc. Except for the elements of the dispenser itself, the viscosity of the glue directly affects the quality of the glue. The higher the viscosity, the smaller the glue point, and even the drawing.

Human needs always occur under specific life scenarios and are strongly influenced by social and cultural concepts. For Internet product managers, you may think that there is no difficulty and technical content in launching a new automatic dispenser. But even so, if you don't understand the changing needs of process automation in the dispensing industry, you can't even develop an automatic dispensing machine. It is very important to understand today's social needs. If you don't comply with customer needs, don't talk about product innovation. Therefore, dispenser manufacturers must have an in-depth understanding of customer experience, understand the changes in consumption concepts, consumption scenarios, and consumer groups, so that automatic dispensers can solve process problems for customers.
