Problems solved by technology

This will cause inconvenient operation of the clamping device, and the clamping gap is not easy to control. When the gap is too large and the thickness of the plate is small, it will easily cause the liquid crystal panel to slip; Too much tension can cause fragments

Embodiment Construction

[0027] The present invention feeds back the clamping force when the clamping member clamps the liquid crystal panel to the controller through the pressure sensor, and judges whether the clamping force reaches the clamping force required by the liquid crystal panel itself through the controller, and controls the The driver continues to drive the lower assembly of the clamping member to clamp the liquid crystal panel or controls the driver to stop driving. This kind of structure makes the clamping force on the liquid crystal panel exactly consistent with the clamping force required by itself, so as to avoid the phenomenon that the liquid crystal panel is broken due to excessive clamping force or the liquid crystal panel is slipped due to too small clamping force , so as to reduce abnormal crashes and will not affect the productivity of the product. Since the preset value can be set in the controller, and the preset value can set different clamping force values ​​according to the...

Abstract

The invention discloses a clamping device and a clamping method thereof. The clamping device used for clamping a liquid crystal panel comprises a clamping member (20), a driver (10) fixedly connected to the clamping member (20), a pressure sensor (30) arranged in the clamping member (20), and a controller electrically connected to the driver (10) and the pressure sensor (30). The driver (10) is used for driving the clamping member (20) to clamp a liquid crystal panel (40). The pressure sensor (30) is used for detecting the clamping force of the clamping member (20) clamping the liquid crystal panel (40) and transmitting to the controller. The controller is used for judging whether the clamping force reaches the preset force or not; if so, the controller controls the driver (10) to stop driving the clamping member (20). The clamping device and the clamping method thereof are capable of preventing the liquid crystal panel from breaking or slipping off.

Description

technical field [0001] The invention relates to a clamping device, in particular to a clamping device and a clamping method for clamping a liquid crystal panel. Background technique [0002] At present, the lifting / falling and closing / opening of the clamping device are all driven by the cylinder, and the body of the clamping device is fixed by a small plastic gasket and a metal block. At present, because the thickness of the liquid crystal panel that needs to be clamped is various, such as the thickness is 0.5mm, 0.7mm, etc., and the thickness of the clamping device needs to be 0.5mm ~ 1.4mm, and because the clamping device's rise / fall , Closing / opening are all controlled by the air cylinder, then the drop sensor of the clamping device and the stop pin for adjusting the clamping gap all need to be adjusted manually by personnel. This will cause inconvenient operation of the clamping device, and the clamping gap is not easy to control. When the gap is too large and the thick...
