[0003] All equipment in the OLED manufacturing industry must ensure the accuracy requirements of OLED devices. Among them, the transfer of the substrate of the OLED device—glass substrate is usually completed by a robot. In an automated production line, this transfer is simple, easy to control, and low in cost, but the transfer The error is large, especially the cumulative error caused by fast transmission or long-distance transmission is particularly prominent
On the existing production line, a positioning mechanism is added to a specific device that implements a position-limited process. Due to the complexity of the structure of the specific device and its electronic system, it is more difficult to add a positioning mechanism, which not only increases the cost of the production line budget, and its precise positioning effect on the glass substrate is not satisfactory

The invention discloses a screw-rod positioning mechanism comprising a soleplate, a lifting plate, a jacking cylinder and two intersected positioning assemblies. Each positioning assembly comprises a motor, a screw rod, a driving device, two screw-rod supporting seats and two moving blocks, wherein the driving device is used for driving the screw rod to rotate; the motor and the screw-rod supporting seats are fixed on the soleplate, and both ends of the screw rod are in opposite rotating directions; either screw-rod supporting seat is provided with a through hole, both ends of the screw rod are respectively and rotatably inserted into the through holes; the moving blocks are provided with screw holes, both ends of the screw rod are respectively, oppositely and movably engaged into the screw holes; and the moving blocks are arranged at the inner sides of the screw-rod supporting seats, and the upper ends of the moving blocks are provided with handspikes in a convex manner. A containingspace for containing a lifting plate is formed among the moving blocks of the positioning assemblies; the edge of the lifting plate is provided with a plurality of jacking columns used for supportinga glass substrate; and the jacking cylinder is fixedly arranged in the containing space. The handspikes on the moving blocks inwards push the glass substrate so as to adjust the position of the glasssubstrate and finally realize the accurate positioning of the glass substrate.
Description
technical field [0001] The invention relates to a positioning mechanism, in particular to a screw positioning mechanism for positioning glass substrates in the organic light emitting diode industry. Background technique [0002] In the display industry of digital products, in order to save energy and reduce production costs, enterprises have increased investment in research and development, and are constantly pursuing new energy-saving products. Among them, OLED display screen is a new product in digital products. OLED is Organic Light-Emitting Diode (Organic Light-Emitting Diode). And it has great market potential. At present, the application of OLED in the world is focused on flat-panel displays, because OLED is the only technology that can be compared with TFT-LCD in application, and it is the only one among all display technologies that can make large-scale display. Size, high brightness, and high-resolution soft screen display technology can be made into the same thick...
