At the transfer module 4, after the second suction nozzle 42 sucks the large mesh cloths on the four first suction nozzles 32, the robotic arm of the injection molding machine sucks the large mesh cloths on the second suction nozzle 42 to complete the automatic loading of the large mesh cloth, and then the fifth rotating shaft 52 rotates and winds the second top film, so that the small mesh cloths on the small mesh cloth belt are exposed, and then the small mesh cloth belt with the second top film removed is passed around the second feeding plate 54 and connected to the sixth rotating shaft 53, and then the four third suction nozzles 62 are driven by the second electric screw 61 to approach the second feeding plate 54, and the four third suction nozzles 62 respectively suck four small mesh cloths from the second feeding plate 54.

Since the injection molding of a workpiece requires a large mesh cloth and two small mesh cloths, the number of small mesh cloth loading mechanisms is two. Then, the workpiece after injection molding is placed on the carrier 93 through the unloading clamps of the injection molding machine, and then is moved out of the earphone shell injection molding mesh automatic loading equipment through the fourth electric screw 92.
