Thermal bonding is to melt the foam surface layer at high temperature with a flame bonding machine, and press the PP plate upward to cool and compound, that is, to bond it with glue. The quality of thermal bonding process is relatively stable, and the effect of composite adhesive will be restricted by climate change.
Nowadays, under the development trend of automation production, automation technology is widely used in modern industrial production. Robots can continuously and repeatedly complete many complex and single processing procedures, and the process is efficient and accurate. At present, in the assembly line production process of notebook computers, there is a process of sticking foam on the back of computer A and D parts. In the past, the production line used to stick foam by hand. However, the above method is time-consuming, laborious and easy to stick. China patent document cn201210317593 discloses a device for sticking foam. The foam sticking device comprises a supporting mechanism, a manipulator, a clamping structure and a foam supply mechanism. The manipulator and the foam supply mechanism are respectively installed on the support mechanism, and the foam supply mechanism is opposite to the manipulator. The clamping structure is installed on the robot hand, and the foam supply mechanism provides foam to the clamping structure. Driven by the manipulator, the clamping structure clamps the foam from the foam supply mechanism to adhere the foam to the workpiece.
