部22によりサイズ別に電磁弁23を制御する。In the figure, a cleaning tank 3 is fixed to a lifting stand 4. The elevating gantry 4 holding the washing tank 3 is guided by a guide shaft 12 via a linear bearing 13, and the elevating gantry 4 is raised by a thrust of a weight 11 via a chain 10, a sprocket 9 and a guide shaft 14, It rises until the sealing surface receiver 7 of the washing tank 3 contacts the panel 1 held stationary. Fifteen
Is a base stand, 16 is a drainage tank, and H is a carrier head.
The elevating gantry 4 constitutes a gantry vertical mechanism together with the cylinder 8. The storage tank 19 attached to the elevating gantry 4 is guided by a guide shaft 18 via a linear bearing 20 and rises by the thrust of a cylinder 17 controlled by a control means. Here, as shown in the piping system of FIG.
The drive of the cylinder 17 is controlled under the adjustment of the solenoid valve 23 by 22 (configured by a piping system including east control valves 24 and 27, a pressure reducing valve 25, and a pressure valve 26 with a filter. This constitutes a tank up-down mechanism for the storage tank 19. A drop is formed between the washing tank 3 and the storage tank 19, and the washing liquid 5 is supplied into the washing tank 3 via the hose 21. Figure 5 is a sectional view showing the details of the panel. constant cleaning liquid into and out of the side surface of the panel 1 height, i.e. cleaning area a 1, a 2 is different by type of the panel 1, to breed detection signal Accordingly, the storage tank 19 is raised, and the control unit 22 controls the solenoid valve 23 for each size.
また、電磁弁23は３位置P,A,B接続タイプを使用し、
貯槽タンク19の中間停止を行なっている。The solenoid valve 23 uses a 3-position P, A, B connection type.
The intermediate stop of the storage tank 19 is performed.

Further, an air hole 6 for bleeding air inside the panel 1 when the panel is immersed in the cleaning liquid 5 of the cleaning tank 3 is provided. The cleaning liquid 5 supplied to the cleaning tank 3 is
In order to stabilize the liquid level, a pressure valve 26 with a filter, a speed control valve 27, and a pressure reducing valve 25 with a check valve in the load direction are attached to reduce the thrust in the load direction to balance the load and stabilize the liquid level.

効果を有する。As described above, by using the cleaning apparatus of the present invention, the level of the cleaning liquid supplied to the cleaning tank can be stabilized, so that waves and bubbles are eliminated, and the defect rate of the graphite film can be reduced by 25% compared to the related art. . Further, since the above-described panel cleaning range can be set arbitrarily, multi-product production can be performed with one apparatus, and a cleaning apparatus having excellent productivity can be obtained. In addition, the use of linear bearings to guide the vertical movement of the elevating gantry eliminates the need for difficult adjustments in order to achieve stable vertical movement, and the number of parts has been greatly reduced, resulting in a 20% reduction in manufacturing costs. It has the effect that it can be done.
