What are the three main factors affecting the glue control q
Release date：2021-08-24 08:55 Views： In the electronic manufacturing industry, there are many places that need professional equipment for dispensing and sealing. When dispensing, the distance between the dispensing needle and the circuit board and the inner diameter of the needle are the most important parameters. If the distance between the needle and the substrate is incorrect, the operator will never get the correct dispensing result. When other parameters remain unchanged, the greater the distance between the dispensing needle and the circuit board, the smaller the diameter of the glue spot and the higher the height of the glue spot; The smaller the distance between the dispensing needle and the circuit board, the larger the glue point diameter and the lower the glue point height.
In fact, there are strict standard dispensing process guidelines on the production line, which can help the production staff better use the equipment to complete the perfect product:
1： Dispensing machine needle size
In practice, the inner diameter of the needle should be about 1 / 2 of the diameter of the dispensing point. In the dispensing process, the dispensing needle should be selected according to the product size. Different needles should be selected for products with different sizes, which can not only ensure the glue dot quality, but also improve the production efficiency.
2： Pressure setting of dispensing machine
The dispensing equipment provides a certain pressure to the needle or glue gun to ensure glue supply. The pressure determines the glue supply and glue outflow speed. Too much pressure is easy to cause glue overflow and too much glue; If the pressure is too low, intermittent dispensing and leakage will occur, resulting in product defects
3： Setting of dispensing time of dispensing machine
The dispensing amount is determined by the setting time of the automatic dispensing machine. In practice, the dispensing setting time should be selected according to the production situation (room temperature, glue viscosity, etc.).
Glue quantity adjustment scheme
Double air hole dispensing controller
Adjust the glue amount according to the machine type
In addition, according to the characteristics of the type of automatic dispensing machine, there will be some other glue quantity adjustment methods, such as the back suction dispensing machine. If the back suction dispensing valve is adopted, there will be a back suction glue action after stopping dispensing. This is also the glue quantity adjustment method, which can keep the glue from leaking. For the glue with low viscosity, it will have a better gluing effect!
The following accessories will be used in the solar frame dispensing of the return suction dispenser: high pressure dispensing valve, dispensing controller, air pressure control device and needle, which are all factors that can directly affect the adjustment of glue amount. Each accessory can be controlled by adjusting the glue amount according to the needs. For example, there are many specifications of dispensing needle. If the specification of needle used for the first time is too large, The specification can be selected according to the dispensing width of the solar frame, the glue amount can be directly adjusted to the same width, and then the precise adjustment can be made by using the dispensing controller. This is the method of adjusting the glue amount of the desktop automatic dispensing machine.
