The invention relates to the technical field of solar cells, in particular to an automatic dispensing chip mounter for manufacturing trays. The automatic dispensing chip mounter comprises a rack assembly, a dispensing assembly, a chip mounting assembly, a conveying assembly and a control assembly, wherein the dispensing assembly is used for dispensing at preset positions of a base plate; the chip mounting assembly is used for automatically attaching blocking pieces to the preset positions of the base plate; the conveying assembly is used for conveying and positioning the base plate; and the control assembly is in signal connection with the dispensing assembly, the chip mounting assembly and the conveying assembly, and controls the dispensing assembly, the chip mounting assembly and the conveying assembly to act. Because the automatic dispensing chip mounter replaces manual tray manufacturing by the dispensing assembly, the chip mounting assembly, the conveying assembly and the control assembly, tray manufacturing period can be shortened by the automatic dispensing chip mounter, and the machining precision is high.
