Embodiment Construction
[0030] In order to further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings and embodiments.
[0031] combine figure 2 and image 3 , the traditional liquid crystal panel pick-and-place frame includes a frame 1, a fixed seat 3, a base 4, and a clip 6. The fixed seat 3 is arranged on the base 4, and the frame 1 is fixed through the fixed seat 3. There is a horizontal direction in the frame 1. A plurality of clips 6 are set, and the liquid crystal panel is placed between two adjacent clips 6. It can also be understood as a slot formed between two adjacent clips 6. Traditionally, Map sensors 5 are arranged on both sides of the frame 1. To detect the state of the LCD panel in the frame. In practical applications, the frame of the module segment usually has more than 60 slots, or even more than 200. Because the slot spacing is very narrow, in continuous production, due to the The move...

The invention discloses a liquid crystal panel detection control method replacing a Map sensor, belonging to the technical field of electric control. In the present invention, after the frame is in place at the working position, the panel state is initialized to full load, and the process computer downloads the panel production information data; for the framework of the working position to pick and place the panel, the definition of the slot is from the direct slot information given to the manipulator, and the definition of the slot is taken Report the current slot information layer by layer for the manipulator until the end of taking the film, and return the initially specified slot information at the same time; the PLC control system sets the slot state when putting the film according to the feedback information of the manipulator, and resets the slot state that has passed when taking the film And clear the information data, and transfer the information data to the manipulator arm when getting it. The invention can realize the safe and reliable handling control of the liquid crystal panel without the Map sensor, and simultaneously saves the purchase cost of the Map sensor.
Description
technical field [0001] The invention relates to the technical field of electric control, in particular to a liquid crystal panel detection control system and method replacing a Map sensor. Background technique [0002] With the development of science and technology, liquid crystal display screens have become the mainstream display devices for electronic products such as TVs, computers, and mobile phones. Liquid crystal display screens are made of liquid crystal panels as raw materials and are produced through a series of complicated processes such as cutting. With the growth of market demand, the size of LCD panels is getting bigger and bigger. At present, they are all fully automatic and unattended intelligent production lines, using manipulators to grab and transfer LCD panels. [0003] As a key sensor detection device for the status of the LCD panel in the frame, the Map sensor is widely used in the LCD panel industry and has strict requirements, as well as fast response...
