Description

Liquid crystal panel transfer device

This creation belongs to the field of transmission technology, especially to the transmission device applied to the LCD panel machine.

According to the technology that has benefited from the LCD panel, the TV is almost completely replaced with the LCD panel of the LCD panel.

Due to the different needs of LCD TVs, TV sets that are currently as small as 32 吋 to 80 皆 have a favorite consumer group. Therefore, TV manufacturers can match the corresponding TV set when assembling the LCD panel of the TV. The basic method of the frame is to share one or two rulers for each fixed one. This method often produces a transmission device with a width that matches the maximum size of the liquid crystal panel, which is for a smaller size. When the liquid crystal panel is assembled, the assembler often does not easily assemble the components due to the length of the arm when assembling the components. Even if the assembly is smooth, the body and the arm are excessively stretched for a long time, causing an occupational injury such as a sore arm. Of course, the industry adopts an adjustable The technical means of the width, but this method is caused by the fact that the transmission device needs to cooperate with the width adjustment device to suspend the operation, thereby affecting the productivity of the liquid crystal panel.

Furthermore, the current transmission device of the liquid crystal panel is mainly composed of a transmission motor, a transmission shaft and a transmission belt, and the transmission motor transmits the transmission belt through the circular transmission shaft to drive the transmission belt to move the liquid crystal panel on the transmission belt; There are also two problems in the design. The first problem is that the transmission belt is a smooth surface. When the liquid crystal panel is placed, it will be smooth with the transmission belt. Full contact and large adhesion, which is obviously not conducive to the removal of the liquid crystal panel from the conveyor belt by the suction cup, and the comprehensiveness of the transmission belt cleaning (because the liquid crystal panel is in full contact with it) is also time consuming; the second problem is If multiple sets of liquid crystal panel machines are to be connected in parallel to form a one-stop production line, since the transmission belt is provided with a smooth surface, the gap between the liquid crystal panel machines increases, and the gap between the liquid crystal panel machines increases. For the current ultra-thin liquid crystal panel, it is easy to drop the gap position when it is transferred to the joint of the machine; and the substrate transfer device of the type disclosed in Taiwan Patent No. I422521 and I536440 only uses the transmission belt and the roller to reach the glass. The substrate transport function, when transporting the ultra-thin mobile phone panel, the panel cannot be pressed down due to the light weight of the panel, which is easy to cause the slippage of the transport belt and the roller to be smoothly lost, and the glass is easily displaced during the transport process. There are serious shortages such as shaking, turning and tilting. On the whole, there are many questions about the above-mentioned conventional glass substrate transport devices. The problem is really necessary to improve.

The main purpose of this creation is to provide a novel liquid crystal panel transfer device that can stop the operation of the liquid crystal panel and simultaneously adjust the width and size of the conveyor belt device.

In order to achieve the above-mentioned intended purpose, the transmission device of the liquid crystal panel of the present invention mainly comprises a conveying device; disposed under the glass carrier of the base body; the conveying device comprises a power source, an output shaft and a plurality of axes The power source is disposed on the main body of the base, the output shaft has a polygonal cross section and is laterally connected to the power source output end and the sleeve; and a conveyor belt device comprises a complex array of two groups. a plate, at least two guiding rods and at least one conveyor belt, wherein a fixed space is formed between the inner sides of each of the two partitions, and each of the plurality of partitioning spaces is provided for the sleeve and a plurality of rollers are further disposed, and An active space is defined between the outer sides of each set of partitions, and the at least two guiding rods extend transversely through the front end and the rear end of the complex array partition, respectively, the conveyor belt has a first end and a second end, the conveyor belt One end of the bushing and the multi-array spacer wound around the conveyor a roller in the fixed space, so that the output shaft drives the rotation time of the sleeve to drive the rotation of the conveyor belt; and an adjusting device is disposed on the base body, the adjusting device includes an adjusting unit, a second power source and a worm, the adjusting unit is disposed in one set of partitions for assembling the second end of the conveyor belt, the adjusting unit can adjust the looseness and tightness of the conveyor belt, and the worm is laterally connected to the second power source and Through the connection of each group of partitions, in order to ensure that the damper is away from or close to each other when the worm is positive or reverse, the spacing of the movable space between each group of partitions (width, narrow) is adjusted; thereby, the conveying device drives the output shaft of the polygon When the conveyor belt device is driven to carry the liquid crystal panel, the adjusting device can be simultaneously activated to change the spacing of the movable spaces between each group of the partition plates, so that the conveying device and the adjusting device can independently drive non-interference persons.

Through the transmission device of the liquid crystal panel composed of the above structure, the expected structural effects include:

First, the transmission device of the present invention drives the conveyor belt to rotate through the output shaft of the polygon, so that the movable space between each group of partitions can be changed by driving the worm forward and reverse through the adjustment device without rotating the conveyor belt. The distance is placed and carried in a liquid crystal panel conforming to the corresponding width.

Secondly, the conveyor belt can perform the first looseness and tightness adjustment through the adjusting unit, and then suck the adjusted conveyor belt downward through a plurality of suction cup suctions disposed under the platform. The second tightness control is formed to make the conveyor belt tighter and less swaying, so that the conveyor belt carries the liquid crystal panel more smoothly.
