Abstract
The invention discloses an anti-jamming device for a circuit board on delivery rollers. A plurality of delivery rollers are fixed on rotating shafts; a clearance is reserved between two adjacent rows of delivery rollers; the anti-jamming device consists of a fixing mechanism and a supporting strip; the supporting strip is provided with a lower surface and an upper surface which are opposite to each other; the lower surface of the supporting strip is arranged on the rotating shaft; the upper surface of the supporting strip is a plane; the supporting strip crosses at least two rotating shafts; the fixing mechanism is connected to at least one of the front end and the rear end of the supporting strip; and the supporting strip is connected to the rotating shaft through the fixing mechanism. By the anti-jamming device, a plurality of rotating shafts are hasped with one another through the supporting strip, so that a printed circuit board can be supported; and a phenomenon that the relatively soft printed circuit board is jammed because the printed circuit board falls into the clearance between two adjacent rows of delivery rollers can be avoided.
Description
Technical field
The present invention relates to a kind of prevent printed circuit board (PCB) clamp at delivery roller during printed circuit board (PCB) is produced
Device.
Background technology
In the production process of printed circuit board (PCB), be circuit board is delivered to by a station by delivery roller it is another
Station, delivery roller is the roller rotated along many rows of direction of transfer distribution, and it is all by being fixed on one often to arrange delivery roller
Multiple rollers of root rotating shaft are constituted, and multiple rows of delivery roller is distributed along direction of transfer, have gap between adjacent row delivery roller,
Suitable for the conveying of printed circuit board.This delivery roller will not be problematic when thicker circuit board is conveyed, but works as
When producing relatively thin circuit board, because circuit board is relatively thin, rigidity is not enough, soft, easily down snaps in the transmission of adjacent row
Between roller, easily cause shutdown, circuit board and scrap, and then affect yield, production efficiency and cost.
The content of the invention
In order to overcome drawbacks described above, the invention provides circuit board antiseize device can effectively be prevented at a kind of print delivery roller
It is only relatively thin printed circuit board (PCB) clamp in course of conveying, and simple structure, easy to implement.
The technical scheme that adopted to solve its technical problem of the present invention is：
A kind of circuit board antiseize device at delivery roller, some delivery rollers are fixed in rotating shaft, adjacent row delivery roller
Between there is gap, the antiseize device is made up of fixed mechanism and support bar, the support bar have relative lower surface and
Upper surface, the lower surface of the support bar is held in rotating shaft, and the upper surface of the support bar is plane, the support bar across
At least two rotating shafts, the fixed mechanism is connected at least one end in the rear and front end of the support bar, and the support bar leads to
Cross the fixed mechanism and be connected to the rotating shaft.
In order to solve its technical problem, the further technical scheme for being adopted is the present invention：
The fixed mechanism is provided with one and positioned at the front end of the support bar.
The fixed mechanism is hook, described to link up with the lower surface for being integrally connected to the support bar, and the hook is stuck in
The rotating shaft.
The hook is provided with one and is integrally connected to the lower surface of the support bar front end.
The lower surface of the support bar is plane.
The upper and lower surface of the support bar is the plane being parallel to each other, and the antiseize device is installed on rotating shaft
Afterwards, the upper surface of the support bar is level.
The antiseize device is installed on after rotating shaft, and the upper surface of the support bar is not higher than the highest of the delivery roller
Point.
The invention has the beneficial effects as follows：The antiseize device of the present invention is made up of fixed mechanism and support bar, and support bar passes through
Fixed mechanism is connected to rotating shaft, and the upper surface of support bar is plane, and across at least two rotating shafts, the present invention is by propping up to support bar
Adjacent many rotating shafts overlap joint is got up to play a supporting role printed circuit board (PCB) by stay, it is to avoid softer printed circuit board (PCB) falls
Enter in the gap between adjacent row delivery roller and cause clamp.
Description of the drawings
Fig. 1 is use state figure of the present invention；
Fig. 2 is antiseize device structural representation of the present invention.
Specific embodiment
The specific embodiment of the present invention is illustrated below by way of specific instantiation, those of ordinary skill in the art are by this
Content disclosed in specification understands easily advantages of the present invention and effect.
