Glass substrate loading frame

The utility model relates to a glass substrate loading frame comprising a frame, an upper cross bar, an upper clamp, a lower cross bar and a lower clamp, wherein the upper cross bar is fixed on the rear surface of the frame; the lower cross bar is fixed on the front surface of the frame; the upper clamp is fixed on the upper cross bar; the lower clamp is fixed on the lower cross bar; at least one upper cross bar and one lower cross bar are arranged on a same glass substrate loading frame; the upper cross bar and the lower cross bar are alternately arranged; the lower cross bar is a square bar; one end of the lower clamp is welded on the upper surface of the lower cross bar; one end, far away from the lower cross bar, of the lower clamp is provided with a U-shaped groove for clamping a glass substrate; and the length direction of the U-shaped groove is consistent with that of the lower cross bar. During use, one end of the glass substrate is clamped in the U-shaped groove of the lower clamp and the other end of the glass substrate is fixed by using the upper clamp, so that even if the lower clamp is thermally deformed, the glass substrate is incapable of falling off; in addition, the lower clamp is welded on the square cross bar and the contact area is large, so that the lower clamp is firmer and the probability that the glass substrate falls off is reduced.
