[0023] Therefore, the focusing structure 10 of the above-mentioned controller can avoid light loss of the lamp beads 14 by focusing the light diverged by the lamp beads 14, thereby improving the light intensity, so that the code reading camera 12 has sufficient light compensation during the code reading process, thereby ensuring the code reading reliability of the code reading camera 12, that is, ensuring the normal operation of the handling robot.
