Embodiment approach

[0045] As an implementation manner, the driving mechanism may only drive the upper suction table to move toward or away from the lower machine table 400 . As another implementation manner, the driving mechanism can also only drive the lower machine table 400 to move toward or away from the upper adsorption table. As yet another implementation manner, the driving mechanism can drive the lower platform 400 and the upper adsorption platform to move simultaneously.

[0046] In order to obtain a better pressing effect, preferably, the box alignment equipment further includes a pressure detection mechanism, which is used to detect the pressure value between the two substrates of the box to be aligned, and the pressure detection The mechanism can send a first control signal to the driving mechanism when the pressure value reaches a predetermined value, and the driving mechanism can stop driving the upper adsorption table and the lower table 400 after receiving the first control signa...

Abstract

The present invention provides an alignment device. The alignment device comprises an alignment cavity, an upper adsorption stage arranged in the alignment cavity, and a lower machine stage which is located in the alignment cavity and is opposite to the upper adsorption stage; the upper adsorption stage includes an upper machine stage and an adsorption layer arranged on the upper machine stage; the alignment device further comprises a plurality of auxiliary adsorption components; each auxiliary adsorption component includes an adsorption disc located at one end of the auxiliary adsorption component; a plurality of through holes are formed in the upper adsorption stage; the through holes pass through the upper machine stage and the adsorption layer; each through hole is corresponding to one auxiliary adsorption component; the adsorption components are arranged in the through holes; and the adsorption surfaces of the adsorption discs are flush with the adsorption surface of the adsorption layer. When the alignment device is adopted to align two substrates, the plurality of auxiliary adsorption components and the adsorption layer can absorb the substrates together, so that the stressed points of the substrates can be increased; and after being stressed, different stressed points coordinate with each other, so that the substrates have little possibility of being deformed.

Description

technical field [0001] The present invention relates to a manufacturing equipment of a display device, in particular to a box aligning equipment. Background technique [0002] A display panel generally includes two oppositely disposed substrates. For example, a liquid crystal display panel includes an array substrate and a color filter substrate. Therefore, one step in manufacturing the display panel is to box the two substrates. [0003] For example, the step of boxing the array substrate and the color filter substrate includes: in a closed vacuum chamber, the array substrate and the color filter substrate are respectively adsorbed by the upper suction table and the lower machine table, and the upper suction table and the lower machine table are driven to move toward each other. , to press the array substrate and the color filter substrate together. [0004] Vacuum suction cups are arranged at intervals on the upper suction platform and the lower platform. When the adsor...
