Clamping device for base plate

Abstract

The invention discloses a clamping device for a base plate, comprising a driving device, a clamping device and a fixing guiding mechanism. The driving device comprises a power supply, a cam provided with two arc guide grooves, and a transmission shaft with one end connected to the power supply and the other end connected to the cam. The clamping device comprises an upper pressure pad, a lower pressure pad, an upper treadle bar, and a lower treadle bar, wherein a circular roller driven member in the two arc guide grooves is respectively disposed on the side walls corresponding to the upper andthe lower pressure pads. A clamping region is formed between the upper and the lower pressure pads. The upper treadle bar is arranged on the upper pressure pad and the lower treadle bar is arranged onthe lower pressure pad. The sliding directions of a guide way and a sliding block are vertical to the upper and the lower pressure pads. The clamping device for base plate has the advantages of stable operation for transmitting and turning over the base plate, simple structure, convenient operation, etc.

Description

technical field [0001] The invention relates to a clamping mechanism, in particular to a substrate clamping mechanism of an organic light-emitting display device.

Problems solved by technology

At present, most of the substrate clamping mechanisms at home and abroad are stepped support mechanisms. This technology is mainly reflected in the Chinese invention patent with the publication number CN1901155A, which discloses a clamper with multiple stepped support plates. The clamper uses the edge to constrain the position of the substrate, so as to realize the clamping of the substrate. The clamper can clamp multiple substrates at the same time, but the clamper can only realize the planar transfer of the substrate, and cannot realize the flipping of the substrate. , and the step-type support mechanism is a plurality of step-type structures, this structure is relatively complicated, and the operation when clamping the substrate is relatively cumbersome

In addition, there is currently a manipulator grabbing mechanism, which uses a vacuum plate to absorb the substrate for transport. Due to the unstable factors of vacuum adsorption, such as damage to the vacuum nozzle and insufficient vacuum, the substrate will be separated from the substrate. There is relative sliding between the clamping mechanisms, so the use of the manipulator grabbing mechanism to clamp the substrate is prone to failure, and even damage to the substrate in severe cases
