The invention relates to an automatic bonding machine for a kitchen range panel assembly. The automatic bonding machine comprises a machine frame with a table top, and further comprises a main positioning hole, a first positioning assembly, a second positioning assembly, a third positioning assembly and a tight pressing assembly; the main positioning hole is formed in the table top and correspondsto a furnace end hole in a panel; the first positioning assembly is used for positioning the panel; the second positioning assembly is used for positioning a metal strip; the third positioning assembly is used for positioning a display panel assembly; and the tight pressing assembly is arranged on the table top, and comprises a rotary tight pressing air cylinder fixed on the table top and a pressing column fixed on a piston rod of the rotary tight pressing air cylinder, and the pressing column can tightly press the panel, the metal strip and the display panel assembly. According to the automatic bonding machine, displacement and dislocation of the panel and other assemblies in the bonding process can be effectively avoided, and correctness of the bonding position of the product can be guaranteed so that the quality of the kitchen range panel product can be improved, in addition, the tight pressing assembly is further arranged, the tight pressing assembly can tightly press the panel, the metal strip and the display panel assembly, then automatic bonding of the panel assembly can be realized, and the processing efficiency is improved.
