Carsette turning over and positioning device

Abstract

The invention is used in rotating a cartridge, and then fixing it. It consists of: a rotating unit located at one side of the cartridge used in rotating the cartridge; a base; movable locating unit containing a locating unit and a rolling component located at one side of rotated cartridge, and the locating component and rolling component are fixed on the base; the rolling component is pops out from the place between locating component and cartridge, used in providing positioning in vertical direction for the rotated cartridge; the location component provides the positioning in horizontal direction for the rotated cartridge.

Description

【Technical field】 [0001] The invention relates to a cassette flipping and positioning device, in particular to a cassette flipping and positioning device suitable for cassettes loaded with large substrates. 【Background technique】 [0002] At present, in a general display panel or chip manufacturing plant, a cassette is used to temporarily store the substrate. Generally, what is most often seen on the production line is that, for example, substrates are stored in batches in cassettes first, and the openings of the cassettes face up to prevent the substrates from falling out. When this batch of substrates is about to undergo a certain manufacturing step, the production personnel will put the cassette into the flipping device, and the flipping device will flip the cassette so that the original upward opening is turned to the side, so as to facilitate the transmission of components on the machine , for example, the robotic arm grabs the substrate in the cassette and enters the ...

Problems solved by technology

However, since the cassette 200 weighs several kilograms, its inertia is large and the acceleration of gravity due to the rotational force, even if the servo motor unit 100 has a loop control, it still takes a long time to make the cassette reach its position after turning the cassette over.

Also, please refer to figure 2 , in order to buffer the impact force of the flipping of the cassette, a buffer 410 is provided on the reference platform 400 to provide a damping effect, and the impact force of the buffer servo motor unit 100 close to the reference platform 400 after flipping the cassette 200, after a period of use, the buffer When the device is aging or the rebound force is not well released, the buffer 410 cannot make the flipped cassette 200 reach the positioning, so that the cassette 200 is often blocked by the positioning stopper 300 before the cassette 200 reaches the positioning. As a result, the cassette 200 cannot be positioned, that is, the support base 12 of the cassette 200 cannot fit the component 42 in place, and there is a gap x between the two. If the substrate is taken out or inserted into the cassette 200 at this time, it will very serious fragmentation problems

In addition, because the conventional cassette flip positioning device only has the positioning effect in the horizontal direction, it is often caused by particles on the edge of the cassette or uneven edge damage, resulting in a vertical positioning error of the cassette, although this error is for small The size of the panel has little effect. However, under the current requirement that large panels must be stacked in high-density cassettes, it is no longer feasible
