Problems solved by technology

[0003] However, in the technology described in Patent Document 1, when the sheet for printed wiring boards is separated, no consideration is given to restricting the sheet for printed wiring boards by contacting the side end portion of the sheet for printed wiring boards. Scraping of contact members such as side rails at the side end surface of the material
[0004] In view of the above circumstances, the present invention aims to provide a sheet separation and conveyance method for printed circuit boards capable of preventing the problem of scraping of contact members such as side rails.

Embodiment approach

[0027] Hereinafter, an embodiment of the present invention (hereinafter referred to as an embodiment) and an embodiment of the present invention will be described in detail with reference to the drawings. In the embodiment example and each embodiment, descriptions of constituent elements (members or components) having the same function and shape, etc., are omitted by assigning the same reference numerals after once description, as long as there is no confusion.

[0028] First, refer to Figure 1 to Figure 4 The separation and conveyance apparatus of the sheet|seat for printed wiring boards which concerns on embodiment example of this invention is demonstrated. figure 1 It is a schematic external perspective view of a separation and conveyance device for a printed circuit board sheet according to an embodiment of the present invention, figure 2 Shown is figure 1 Appearance perspective view of the separating and conveying device for printed circuit board sheets, image 3 Sho...

Embodiment approach 1

[0063] For the separating and conveying device for a printed wiring board sheet having the method of separating and conveying a printed wiring board sheet according to Embodiment 1 of the present invention and the holding part for implementing the method, the method for separating and conveying a printed wiring board sheet different from that of the embodiment example is used. The point of the sheet separating and conveying device 130 will be centered on the description. Figure 8 Shown is a partial cross-sectional side view of the floating holding conveying device constituting the separating conveying device for printed circuit board sheets used in Embodiment 1, Figure 9 Shown is a perspective view of the floating holding transfer device seen obliquely from the lower right. Figure 10 Shown is a perspective view illustrating belt holding regions of a plurality of conveyor belts of the floating holding conveyor device. Figure 11 Shown is a front view of the separated state ...

Deformed example 1

[0079] pass Figure 14 Modification 1 of Embodiment 1 will now be described. Figure 14 (a) is a front view of a separation and conveyance device for a printed wiring board sheet according to Modification 1 of Embodiment 1, Figure 14 (b) is a schematic front view showing the width of the printed wiring board sheet held by suction on the conveyor belt having a step according to Modification 1. FIG. Figure 14 The separation and conveyance apparatus 130B of the printed circuit board sheet shown in (a) and Figure 8 to Figure 12 Compared with the printed circuit board sheet separating and conveying device 130A, the difference is only that a plurality of (three in the illustrated example) floating holding and conveying devices 160A of Embodiment 1 are arranged side by side in the width direction Y. Thereby, the separating and conveying apparatus 130B of the printed wiring board sheet can float, separate, suck and hold, and convey, for example, a large-sized printed wiring board...

Abstract

The invention relates to a seperation convying method and a seperation convying device for sheet materials for a printed circuit board. The sheet material seperation device (130A) of the printed circuit board comprises an air ejection mechanism which ejects air toward a stacked sheet materials of the printed circuit boad and ejects air on the end of the sheet material of the printed circuit board and a retaining mechanism maintaining the sheet materials of the printed circuit board which are afloat and seperating the sheet materials of the printed circuit board; the retaining member has retaining parts like retaining units (165). Compared with the direction width of a convying direction of the sheet materials of the circuit board which are perpendicular to the stacked of the sheet materials of the printed circuit board, the sheet materials of the printed circuit board are maintained in a manner that the width of the sheet material of the printed circuit board is reduced

Description

technical field [0001] The present invention relates to a method for separating and conveying sheets for printed circuit boards, a device for separating and conveying sheets for printed circuit boards, a method for separating and conveying prepregs, and a device for separating and conveying prepregs. Background technique [0002] Conventionally, a prepreg apparatus and method capable of separating and conveying a prepreg are known (for example, Patent Document 1). Patent Document 1 discloses the following prepreg supply device and prepreg supply method. That is, in this document, the end of the first page of the stacked prepregs as the suction portion is sucked and lifted (moved upward) by a suction pad that reciprocates by a cylinder or the like, and is further passed by another The adsorption pad that moves up and down by the cylinder absorbs and lifts the end of the second page. Next, both suction pads are simultaneously moved horizontally, for example, by about 50 mm t...
