The invention discloses an automatic
power test machine for an ultra-thin
heat pipe and a working method thereof. The automatic
power test machine comprise a rack, a material lifting mechanism, a material height detection mechanism, a feeding mechanism, a
test fixture mechanism, a program-controlled direct-current power supply and a PLC (
programmable logic controller); the material height detection mechanism is provided with a trough, a material sensor and a
photoelectric sensor, the material sensor is used for sensing whether materials exist in the trough, the
photoelectric sensor is used fordetecting the height of the
heat pipe in the trough, and the material lifting mechanism is used for maintaining the
heat pipe in the trough at an appointed height; the feeding mechanism is arranged on a substrate, the feeding mechanism is provided with a vacuum sucker, and the feeding mechanism is used for realizing feeding and blanking of the heat
pipe through the vacuum sucker; the test fixturemechanism is provided with a heat
pipe placing block and a
temperature sensing block, the heat
pipe placing block is provided with a heating block and a cooling block, the feeding mechanism is used for placing the heat pipe on the heat pipe placing block through the vacuum sucker, one end of the heat pipe is in contact with the heating block, the other end of the heat pipe is in contact with thecooling block, the
temperature sensing block is electrically connected with a temperature acquisition card, and the
temperature sensing block is used for acquiring temperatures at two ends of the heatpipe.
