Power-on carrying apparatuses and alignment ultraviolet liquid crystal irradiation devices

A power-on carrying apparatus, configured to carry a power-on probe to power on a display substrate, the power-on carrying apparatus comprising:

• a base including a second through hole configured to fix a power connector, and the power connector is fixed to the base by mating a second fastener and the second through hole, and is configured to supply power to the power-on probe;
• and
• a carrying mechanism, arranged on the base and capable of moving relative to a power-on contact of the display substrate, wherein the carrying mechanism comprises a sliding rail arranged on the base and at least one sliding block arranged on the sliding rail, the at least one sliding block is able to move at any position on the sliding rail, and the power-on probe is fixed at a top of the at least one sliding block to move with the at least one sliding block along the sliding rail, so as to enlarge an adjustment range of the power-on probe;
• and a positioning structure is arranged on the at least one sliding block, and the at least one sliding block is fixed to the sliding rail through the positioning structure, to increase an adjustment accuracy of the power-on probe.
