Description

Floating rolling wheel structure

This creation is related to a floating rolling wheel structure, especially a kind of thin plate that can be clamped and passed through, and the rolling wheel can be automatically raised or lowered to adjust the gap between the rolling wheel and the active roller below By.

In the manufacturing process of printed circuit boards, before the substrate is exposed, a photoresist layer and a film adhered to the surface of the photoresist layer are formed on the upper and lower surfaces of the substrate, respectively. After the exposure, the film is peeled off to make the photoresist The layer is exposed for subsequent development and etching procedures. The existing film stripping machine peels off the film mainly through a front conveying section to convey the above-mentioned printed circuit board and the like, so that it moves in the conveying direction from front to back to a rear conveying section, and then a set of The adhesive wheels or belt pulleys gradually peel off the wrinkled film on the front edge of the sheet. During the conveying process of the thin plate, in order to provide effective guidance and prevent the deformation of the plate body of the thin plate or the upturning of the front edge, a plurality of slave rollers are arranged above the active rollers arranged horizontally in the front conveying section. The movable rolling wheel is used to clamp the thin plate between a plurality of driving rollers and a plurality of driven rolling wheels to prevent the thin plate from flexing and deforming, and to drive the thin plate to move back smoothly to peel off the film.

However, in the actual process of peeling off the film, it was found that when the gap between the plurality of driving rollers and the plurality of driven rollers is fixed, although the thin plate can be effectively clamped and the thin plate is driven to move back smoothly, but with The refinement of the manufacturing process requires a thinner printed circuit board, When the thickness is thinner, the printed circuit board is more likely to be flexed. In this way, according to the existing fixed gap arrangement of the driving roller and the driven roller, the printed circuit board is The front end is easily pressed against the rolling wheel due to upward bending, and bends due to instantaneous pressing, which affects the subsequent film peeling operation. Furthermore, the gap between the plurality of driving rollers and the plurality of driven rolling wheels is fixed, which can only be applied to thin plates with a fixed thickness range during operation. For thicker or thinner sheets beyond the thickness range, the height of the rolling wheel must be manually adjusted to make the gap between the driving roller and the driven rolling wheel appropriate.

In view of this, in order to provide a structure that is different from the conventional technology and improve the above-mentioned shortcomings, the creators have accumulated years of experience and continuous research and development and improvement, and this creation was born.

One purpose of this creation is to provide a floating rolling wheel structure, which can solve the gap between the conventional driving roller and the driven rolling wheel, so that the front end of the thin plate is easy to bend due to pressing against the rolling wheel, which affects the follow-up The film peeling operation and the problem that it cannot be applied to the thin plate beyond the fixed thickness range and need to be adjusted manually, and the plurality of driven rollers can automatically rise or fall according to the thickness of the thin plate to reduce the resistance of the front end of the thin plate The amount of pressure allows the sheet to move completely and smoothly; and it is flexible to apply to sheets of different thickness specifications to save labor time.

In implementation, the first positioning portion and the second positioning portion are respectively vertical long grooves.

When implemented, this creation further includes a first connecting piece, one side of the first connecting piece is connected to one end of at least two rolling wheels, the other side of the first connecting piece has a first pivot, and the first positioning part is One end of the first pivot of the upright long slot is limited in the first positioning portion.

In implementation, one end of the at least two rolling wheels is connected to one side of the first connecting member in a horizontally spaced manner, and the first pivot is connected to the middle section of the other side of the first connecting member.

In implementation, this creation further includes a second connecting piece, one side of the second connecting piece is connected to the other end of at least two rolling wheels, the other side of the second connecting piece has a second pivot, and the second positioning part is It is an upright long slot, and one end of the second pivot is limited in the second positioning part.
