Problems solved by technology

[0009] The technical problem to be solved by the present invention is to provide a flipping device and method, which is convenient for clamping liquid crystal panels of different sizes and thicknesses, and at the same time shortens the working time for changing the line, so as to improve the flexibility of the production line so that it can be produced flexibly, and can solve the problems caused by air pressure. The problem that the low reliability of the action makes the flipping fragment rate too high

Embodiment Construction

[0038] The preferred embodiments of the present invention and their effects are described as follows in conjunction with the drawings.

[0039] As shown in FIG. 5 and FIG. 6 , a flipping device 40 is disclosed for the present invention.

[0040] The turning device 40 includes: a bracket 41 , a plurality of clamping arms 42 , a clamping unit 43 , a transmission mechanism 44 , a turning mechanism 45 , and a control device 46 .

[0041] The bracket 41 is used for lifting and lowering, and a horizontal rail 411 is provided on the bracket 41 .

[0042] A plurality of clamping arms 42 are located on both sides of the support 41. The clamping arms 42 move up and down along with the support 41, and move laterally along the track 411 on the support 41, and there is a housing between the multiple clamping arms 42. There is room for the panel 50 to be placed.

[0043] The clamping unit 43 is located at one end of the clamping arm 42 , and the clamping unit 43 has an upper jaw 431 and a...

Abstract

A tilting device includes a support, a number of gripper arms, a gripping unit, a drive unit and an overturn unit and a control unit with a man-machine interface, in which, at least one point of positioning-information is input, and then the device can drive the support and the machine to move for gripping according to the positioning information. A kind of overturning method includes the following steps: it loads one positioning-information into the controlling unit, then it drives one support and the transmission unit, then it drives a number of gripper arms to a lower location, then it moves the arm in a horizontal direction to the side of an item, then the transmission unit drives a number of fixed gripping units to gripe the item, then it drives a number of gripper arms to the higher location, then a turning machine drives the gripping unit overturns around an axis, then it drives the gripper arm to the lower location, and the gripping unit looses the panel.

Description

technical field [0001] The invention relates to an overturning device and method, in particular to an overturning device and method for clamping and overturning different panels. Background technique [0002] In the manufacturing process of the liquid crystal display, in order to process the front and back sides of the liquid crystal panel, two different workstations are mostly used for processing respectively. The liquid crystal panel is turned over by a panel turning device between the two workstations, so that the liquid crystal panel can be turned over to the other side for processing by the other workstation after finishing processing at one of the workstations. [0003] As shown in Figure 1, it is an existing panel turning device, which is provided with a pneumatic cylinder 10 with a sensing element 101, and a hollow rotating shaft 11 is connected to one side of the pneumatic cylinder 10, and can be rotated by the pneumatic cylinder 10 One hundred and eighty degrees. ...
