Abstract

Provided is a tray rotary-type chamber for plant cultivation, which comprises a base frame, a plant cultivation part, a chamber housing, a water supply member, a nutrient solution supply member, a temperature sensor and a humidity sensor, a hot air supply means, and a cold air supply means, so as to enable not only cultivation of a small number of plants by a chamber having a small volume but also smooth cultivation of a large number of plants by continuously arranged multiple chambers and enable an internal condition of the chamber to be maintained in an optimal condition according a plant to be cultivated. Therefore, the present invention can maximize cultivation efficiency relative to a minimum installation area thereof and also maximally increase the amount of cultivated plants.

Abstract

Provided is a pallet for OLED panel inspection, in which an FPCB is formed to be divided into a contact FPCB which is in contact with an OLED panel and a connection FPCB which is connected to a PCB board connected to a pallet body such that instead of replacing the entire pallet or the entire FPCB by withdrawing the pallet from inspection equipment depending on the OLED panel to be inspected, it is possible to replace and use only each clamp block on which an FPCB corresponding to the OLED panel to be inspected is mounted. After the tip end and the tail end of the contact FPCB and the connection FPCB corresponding to each other are in contact with each other, the contact FPCB and the connection FPCB are coupled onto a mounting block of the pallet body and then are coupled and fixed onto a detachable clamp block which can be loaded and unloaded by a lever. Thus, the present invention has an effect of being capable of quickly performing an inspection in a short time without onerousness or inconvenience even when inspecting other OLED panels to be inspected, thereby maximizing inspection efficiency.
