The number of the second fans is three. Three second trays can be placed on the third carrier. One second tray corresponds to one second fan.

[0039] Movement process: First, the vibrating bowl 11 sorts the workpieces inside through its own vibration. At this time, the concave end of the workpiece faces upward. Then, the feeding robotic arm 12 drives the first suction cup 1 to pick up the sorted workpieces and snap the convex end of the workpiece into the first tray located on the first carrier 22. After the first tray is filled with workpieces, it moves to the first handling mechanism 3 under the drive of the first cylinder 21. Then, the second suction cup picks up the first tray and moves to the first dispensing machine under the drive of the first robotic arm. The first dispensing machine dispenses glue on the workpieces. After the glue dispensing is completed, the first tray moves to the second carrier 51 of the first placement platform 5 under the drive of the first robotic arm. The first fan 52 blows air on the workpieces on the first tray to increase the drying speed of the glue. After the glue dries, the first tray moves to the fourth carrier 91 of the turning mechanism 9 under the drive of the first robotic arm. The cylinder rod of the clamping cylinder 95 extends to clamp the first tray. An empty second tray is placed on the fifth carrier 92. Then, the second tray moves to directly below the first tray under the drive of the second cylinder 94. The first tray rotates under the drive of the rotation motor 96. At this time, the workpieces on the first tray face the second tray. Then, the second tray moves closer to the first tray in the vertical direction under the drive of the third cylinder until the concave end of the workpiece snaps onto the protrusion of the second tray. Then, the second tray returns to its original position under the drive of the third cylinder. Since the convex end of the workpiece is snapped into the groove of the first tray, the workpiece will not fall off when the first tray rotates. Additionally, since the tightness of the concave end of the workpiece snapped onto the protrusion of the second tray is greater than the tightness of the convex end of the workpiece snapped into the groove of the first tray, the convex end of the workpiece can be disengaged from the groove of the first tray when the second tray returns to its original position under the drive of the third cylinder. Then, the second tray returns to its original position under the drive of the second cylinder 94. The third suction cup picks up the second tray and moves to the second dispensing machine under the drive of the second robotic arm. The second dispensing machine performs secondary glue dispensing on the workpieces on the second tray. Then, the second tray moves to the third carrier of the second placement platform 8 under the drive of the second robotic arm. The second fan blows air on the second tray to increase the drying speed of the glue. When the glue dries, the second tray moves to the sixth carrier 102 of the ejecting mechanism 10 under the drive of the second robotic arm. Then, the ejector pin extends from the through hole in the middle of the protrusion under the drive of the ejecting cylinder 103 to eject the concave end of the workpiece out of the protrusion. Then, the fourth suction cup 202 picks up the workpiece ejected from the protrusion. Then, the workpiece moves to the discharging position under the drive of the second electric lead screw 201. The fourth suction cup 202 puts down the workpiece, thus completing the automatic glue dispensing and discharging of the workpiece.

[0040] Using the automatic glue dispensing equipment in this embodiment has the advantages of high automation, high glue dispensing efficiency, and high glue dispensing accuracy.
