When the diode power module is vacuum-adsorbed by the suction pen mechanism 82 and pressed down into the second groove of the second positioning guide mold 42, the second positioning guide mold 42 is driven to rotate by the rotating motor 41, thereby rotating the diode power module to the desired direction; the function of this mechanism is to rotate the diode power module to the desired direction.

Then the material blocking cylinder returns the product and slides down into the tube. When the tube is full, the transport motor transports the full tube feeding cylinder. When it reaches the bottom of the full material pipe, the full material pipe feeding cylinder pushes up to drive the full material pipe supporting block to send the full material pipe to the material pipe supporting block platform. After the full material pipe feeding cylinder retreats, the transport motor transports the empty material pipe feeding cylinder to the bottom of the empty material pipe silo, the cylinder pushes up the empty material pipe supporting block to support the empty material pipe, and the empty material pipe supporting cylinder retreats.
