Description

A panel conveyor that can adjust the width of the conveyor rail wheels synchronously

technical field

The utility model relates to a board conveyer capable of synchronously adjusting the width of conveying rail wheels, in particular to a board conveyor that can synchronously drive each sliding conveyor on the same side of the board conveyer when the rotation of the drive shaft is adjusted. The rail wheel approaches or moves away from the conveying rail wheel on the other side to adjust the width of the panel conveyor used to transport the panels, thereby making it easier, more convenient, and more accurate to adjust the width.

Background technique

Based on the requirements for product quality improvement, the current manufacturing of traditional circuit boards is increasingly oriented towards ultra-density fine lines and micro-blind vias. Therefore, the use of high-density interconnection (High Density Interconnection, referred to as HDI) substrates is currently a common practice, and in During the manufacturing process, the cleaning requirements for HDI substrates are becoming increasingly stringent. The traditional conveyor used to transport boards is shown in Figure 6. It is equipped with a plurality of parallel lower conveying axes C in the mechanism, and the lower conveying axis C On the upper conveying shaft D above, each of the lower conveying shaft C and the upper conveying shaft D is provided with a plurality of lower conveying rail wheels C1 and upper conveying rail wheels D1, as well as a lower gear C2 and an upper gear D2, and on the lower conveying shaft C One end is provided with a driven gear B, which meshes with the driving gear A combined with the drive shaft. When the driving gear A is driven to rotate, it drives the driven gear B to rotate the lower conveying shaft C and the lower conveying rail wheel C1, and The lower gear C2 then drives the upper gear D2 to make the upper conveying shaft D rotate synchronously with the upper conveying rail wheels D1, and the plate 5 is clamped and transported between the upper and lower conveying rail wheels D1 and C1. Since the traditional conveyor shown in Figure 6 has a large number of upper and lower conveying rail wheels D1 and C1, the conveying rail wheels are easily attached by cleaning liquid or impurities on the plate, and then the conveying rail wheels will Impurities are attached to the next panel, thus causing a vicious circle. Because the traditional panel conveyor has a high risk of contaminating the panel, it is no longer suitable for the delivery of precision HDI panels.

At present, the method used to transport precision liquid crystal display panels (LCD) is to use a non-contact panel conveyor. The attached impurities are then attached to the LCD, so it is used in conveyors for conveying LCDs, and is also used for conveying HDI substrates.

Since the boards conveyed by the board conveyor may have more than one size, it is often necessary to adjust the width between the outermost two conveying rail wheels on the conveyor according to the different sizes of the boards to be conveyed. However, since the above-mentioned traditional conveying rail wheels of the panel conveyor are locked on each conveying shaft one by one with screws, if the width distance between the conveying rail wheels is to be adjusted, the same side must be screwed one by one. After loosening each conveying rail wheel, adjust the position, and then tighten it; in this way, it will not only consume a lot of manpower and time but is not economical, and the adjusted displacement of each conveying rail wheel will also produce relatively large Large error, poor accuracy.
