Description

Thin-plate centering device on bare-space conveying line

The invention relates to a transfer technology of a printed circuit board in a manufacturing process, and in particular relates to a thin-plate centering device on a bare-space conveying line.

It is well known that during the manufacturing process of printed circuit boards (PCBs), they need to be transferred to different working area stations to receive multiple processes such as drilling, coating of ink, ink plugging, and baking. When printed circuit boards are in different working areas, When moving from station to station, different conveyor lines are used.

For example, when a printed circuit board accepts an ink plugging operation, the two ends of the printed circuit board that has been coated with ink are generally contacted by two rollers, respectively, so that the two end surfaces of the printed circuit board and the through holes and buried holes are buried. Excess ink in the hole can be taken off the double-end surface of the printed circuit board by rolling and sticking. Since both ends of the printed circuit board have been coated with ink, it is carried by a bare-space type conveyor line.

The so-called bare-type conveying line refers to the carrying elements (for example, driving rollers and conveyor belts) constituting the conveying line, which are respectively arranged at two opposite ends of the conveying line, and make the bare elements formed between the opposite ends of the carrying elements. form. In this way, the printed circuit board is transported by using such a bare-space type conveying line, so that the board body coated with the ink in the middle of the printed circuit board can be suspended, so as to prevent the carrier components from contaminating the ink coated in the middle area of the printed circuit board. . In other words, the two opposite ends of the printed circuit board are usually left blank without ink, so that the printed circuit board can accept the clamping of the clamping claws or the support and transmission of the above-mentioned carrier components.

Moreover, it is known that the general bare-space conveying line is only suitable for conveying the plate thickness between For printed circuit boards with a thickness of 1 mm or more, if the thickness of the printed circuit board is less than 1 mm (that is, the board is too thin, hereinafter referred to as "thin board"), it is easy to make the board body (that is, the board) bridged between two opposite ends (The middle region of the body).

As shown in FIG. 1, when the thin plate 50 a is placed on the bare-type conveying line 10 a, only the two opposite ends of the thin plate 50 a are supported, so that the plate body in the middle region of the thin plate 50 a has a phenomenon of arc collapse. As shown in FIG. 2 again, it is revealed that the thin plate 50a that is being transported in the state of FIG. 1 is difficult to be smoothly coated by two ink rollers due to its curved and collapsed plate body when the ink plugging operation is to be performed. The capture opening 20a formed between 21a captures, and a material jam phenomenon occurs, which affects the proper rate of the ink plugging operation. It can be seen that today's bare-space conveying lines are not suitable for conveying thin plates with a thickness of less than 1 mm.

In view of this, the purpose of this new model is to improve the problem that the thin plate is prone to arc collapse when it is transferred using a bare-type conveying line, and it is difficult to properly accept the extraction at the end of the conveying line.

In order to solve the above-mentioned problems, the present invention provides a thin plate centering device on a bare-air conveying line, including: a plurality of carrying elements, which are constructed in a manner of being spaced on both sides to form the conveying line. A bare empty area is formed between the components, and the sheet accepts the transfer movement in such a way that the sheet is suspended in the bare empty area in the middle and bridged on both sides by the plurality of carrying components; a picking port is formed on one of the conveying lines At the end, for capturing the thin plate on the conveying line; at least one air vent is disposed between the carrying elements and adjacent to the taking port; wherein the air vent is disposed in the bare space of the conveying line and Blow upwards to straighten the sheet.

In a further implementation, the air injection port is formed on an air supply bar. The air supply bar is disposed at a middle position of the bare space. The number of the air supply bars is multiple, and the air supply bars are arranged at intervals in the bare space.

In a further implementation, the carrying element is a driving roller. The driving roller has a conical surface, and the conical surface provides end-to-edge contact of the thin plate.

In a further implementation, the carrying element is a conveyor belt.

In a further implementation, the extraction opening is formed between two vertically arranged rollers. Wherein, the two rollers are respectively provided with an adhesive film, and when the picking mouth is used to pick up the sheet, the two rollers are pressed against the sheet through the adhesive film respectively. The extraction opening is a straight narrow opening.

In a further implementation, the extraction opening is formed on a platform surface of a flat platform.

In a further implementation, a stopper is further included, and the conveying line is located between the stopper and the air outlet.

According to the above technical means, the technical effect that the new model can produce is: by using the gas blown from the gas jet port to apply a thrust to the thin plate, the arc-collapsed portion of the thin plate can be straightened into a linear plane shape during the transmission process, so as to facilitate the thin plate It can smoothly accept the picking of the picking mouth and leave the conveying line, which can effectively avoid the phenomenon of sheet material jamming due to the arc-collapsed part.

The new model has been verified by experiments that with the proper configuration of the number of air outlets and the proper configuration of the layout, it can be suitable for thin plates with a general plate thickness of more than 0.1mm to receive the stable transmission of bare-space conveying lines without the occurrence of plate arc collapse. , Especially when the sheet is picked at the end of the bare-conveyor line by the picking port between the two rollers, or when the sheet is automatically transferred to the table of a flat platform at the end of the bare-conveyor line, both Can effectively improve the acceptance rate of the thin plate to accept or place.

In addition, related technical details on which the new model can be implemented will be explained in subsequent implementations and drawings.
