The utility model relates to the technical field of
electric control testing, and discloses a
production line tray loading device which comprises a
base station, a bottom frame is arranged above the
base station, an upper pressing plate is hinged to the right end of the bottom frame, and a water path
assembly is arranged between the bottom frame and the upper pressing plate. The water way
assembly comprises two first water openings formed in the upper surface of the base table and a second water opening formed in the upper surface of the upper pressing plate. According to the
production line carrying disc device and the waterway
assembly, efficient circulation and flexible
path switching of
water flow among multiple channels are achieved through the innovatively-designed
water gap switching valve, the commutation speed and the
system response efficiency are remarkably improved, the direct-current high-
voltage plug-in unit is designed to be of a floating structure, the connection requirements of different positions can be self-adapted, and the service life of the direct-current high-
voltage plug-in unit is prolonged. The assembling tolerance is effectively compensated while high-precision
butt joint is ensured, the
system reliability is improved, finally, the pressing assembly applies uniform pressure to the circuit board between the bottom frame and the upper pressing plate by flexibly clamping the circuit board, and the stability of the circuit board in high-speed operation is ensured.
