When the clamping plate 1 4c and the clamping plate 2 4d are in a clamped state, they are in the form of a circular hoop tightly attached to the outer surface of the crucible 5. When the clamping plate 1 4c and the clamping plate 2 4d are in a loose state, they are in the form of two semicircles leaving the outer surface of the crucible 5.

[0026] The working principle of the automatic transfer device for solder alloy melt of the present invention is as follows: when the automatic transfer device for solder alloy melt is working, the power supply circuit 7 supplies power to the entire control system, and the PLC programmable controller 6a drives the motor 2 3c3 to rotate forward by the motor 2 control circuit 3c31 to drive the clamping arm 1 4a and the clamping arm 2 4b and the clamping plate 1 4c and the clamping plate 2 4d to clamp the crucible 5 containing the solder alloy melt, and when the clamp is clamped in place, the photoelectric sensor switch 11 senses the cross bar 1 4a1 and inputs a clamping in place information to the PLC programmable controller 6a, and the PLC programmable controller 6a immediately cuts off the motor 2 control circuit 3c31, and the motor 2 3c3 stops rotating at the same time, and then the PLC programmable controller 6a drives the hydraulic control system 14 to drive the hydraulic rod 3 e performs an ascending action; when the piston rod 3e2 rises to the position, the PLC programmable controller 6a drives the motor 1d1 to rotate forward through the motor 1 control circuit 1d11 and the frequency converter 6e to drive the crucible transport mechanism 2 and the crucible 5 containing the solder alloy melt to move forward. When the photoelectric sensor switch 9 fixed on the bracket cross frame 1b senses the crucible transport mechanism 2, it inputs a forward signal to the PLC programmable controller 6a. The PLC programmable controller 6a immediately cuts off the power supply of the motor 1 control circuit 1d11, and the motor 1d1 stops. Then the PLC programmable controller 6a drives the motor 3 4f to rotate forward by supplying power to the motor 3 control circuit 4f1, and drives the clamp 1 4c, the clamp 2 4d and the crucible 5 to rotate slowly forward to pour out the alloy melt.When the crucible 5 rotates about 120 degrees, the limit rod 3 4d11 on the clamp plate 2 4d hits the tipping position limit switch 13 fixed on the clamp arm 2 4b, the tipping position limit switch 13 inputs a tipping position signal to the PLC programmable controller 6a, and the PLC programmable controller 6a immediately cuts off the power supply of the motor 3 control circuit 4f1, the motor 3 4f stops and waits for about 15 seconds until all the solder alloy melt in the crucible 5 is poured out, the PLC programmable controller 6a drives the motor 3 4f to reverse by supplying power to the motor 3 control circuit 4f1, and drives the clamp plate 1 4c, the clamp plate 2 4d and the crucible 5 to rotate slowly backward, when the limit rod 3 4d11 on the clamp plate 2 4d hits the return position limit switch 12 fixed on the clamp arm 2 4b, the return position limit switch 12 inputs a return position signal to the PLC programmable controller 6a, the PLC programmable controller 6a immediately cuts off the power supply of the motor 3 control circuit 4f1, the motor 3 4f stops, and then the PLC programmable controller 6a The PLC 6a drives the motor 1d1 to reversely drive the crucible transport mechanism 2 and the empty crucible 5 by supplying power to the motor 1 control circuit 1d11 and the frequency converter 6e. When the photoelectric induction switch 8 fixed on the bracket horizontal frame 1b senses the crucible transport mechanism 2, it inputs a signal of retreating to the PLC 6a. The PLC 6a immediately cuts off the power supply of the motor 1 control circuit 1d11, and the motor 1d1 stops. Then the PLC 6a drives the hydraulic control system 14 to lower the hydraulic rod 3e. When the piston rod 3e2 drops to the right position, the PLC 6a drives the motor 2 3c3 to reversely drive the clamping arm 1 4a and the clamping arm 2 4b and the clamping plate 1 4c and the clamping plate 2 4d to release the empty crucible 5. At this time, the automatic control system completes a set of automatic transportation of the solder alloy melt and waits for the next round of solder alloy melt to be transported. ;

That is, all simple equivalent changes and modifications made according to the scope of the patent application and the content of the specification of the present invention are still within the scope of the present invention.
