The invention discloses minisize optical product assembling equipment and method. The assembling equipment comprises a material carrying assembly, an assembling assembly and a first shooting detectionassembly. The material carrying assembly comprises a first tool and a second tool; the first tool is used for bearing a first material, and the second tool is used for bearing a second material; andthe material carrying assembly is configured to be used for carrying the first material and the second material to preset positions. The assembling assembly is provided with a grabbing mechanism; andthe grabbing mechanism is configured to be capable of grabbing the second material from the second tool and assembling the second material onto the first material located in the first tool. The assembling assembly is configured to be capable of aligning the second material with the first shooting detection assembly before the second material is assembled onto the first material; the first shootingdetection assembly is configured to detect the posture of the second material; and if the posture of the second material does not conform to second preset posture, the grabbing mechanism is driven toconduct calibration adjustment on the posture of the second material.
