Electronic automatic dispensing machine
Technical Field
The utility model relates to a point gum machine field specifically is an electronic automation point gum machine.
Background
The more and more the dispensing process is in industrial production, the more and more strict the requirements are. The traditional glue dispensing is manually operated by workers, and with the rapid development of automation technology, the manual glue dispensing is far from meeting the industrial requirements and is gradually replaced by an automatic glue dispenser. The automatic glue dispenser is widely applied to industrial production, such as integrated circuits, printed circuit boards, electronic components, automobile parts, handbags, packing boxes and the like. The application of the automatic glue dispenser improves the production efficiency to a great extent, improves the product quality, and can realize certain processes which can not be finished by manual glue dispensing. In order to communicate with the dispensing robot simply and conveniently, people transmit ideas to the robot, and the robot moves according to the intention of the people and the requirements of the dispensing process, the teaching programmer system is invented. The teaching programmer can simply control the dispensing robot, send various motion instructions and execute dispensing of various graphs.
At present, after a spray head of a glue gun is used for dispensing glue, the liquid of colloid has viscosity, and the glue gun does not have a function of sucking back glue, so that the situation that a small amount of glue is gathered at the spray head is avoided, and after the glue is dispensed, the small amount of glue of the spray head can be adhered to elements of a circuit board to cause glue drawing.
