Abstract
The utility model discloses a delivery roller circuit board clamp prevention device. A plurality of delivery rollers are fixed on rotating shafts, and gaps are reserved between adjacent rows of delivery rollers. The clamp prevention device is formed by a fixed mechanism and a support strip, wherein the support strip has the lower surface and the upper surface which are opposite, the lower surface of the support strip is arranged on the rotating shaft, the upper surface of the support strip is a plane, the support strip stretches across at least two rotating shafts, the fixed mechanism is connected with at least one end of the front end and the rear end of the support strip, and the support strip is connected on the rotating shafts through the fixed mechanism. The support strip enables a plurality of adjacent rotating shafts to be in lap joint to support printed circuit boards, and soft printed circuit boards are prevented from falling into the gaps between the adjacent rows of delivery rollers to cause board clamp.
Description
Technical field
The utility model relates to a kind of printed circuit board (PCB) that prevents at the device of delivery roller place clamp in the printed circuit board (PCB) production process.
Background technology
In the production process of printed circuit board (PCB), by delivery roller circuit card is delivered to another station by a station, delivery roller is the roller that rotates along a lot of rows that direction of transfer distributes, every row's delivery roller all is to be made of a plurality of rollers that are fixed in a rotating shaft, many row's delivery rollers distribute along direction of transfer, have the gap between adjacent row's delivery roller, be applicable to the conveying of printed circuit board.This delivery roller does not have problem when carrying thicker circuit card; but when producing thinner circuit card; because circuit card is thinner; rigidity is inadequate; soft; down snap between adjacent row's the delivery roller easily, cause that easily shutdown, circuit card are scrapped etc., and then affect yield, production efficiency and cost.
The utility model content
In order to overcome defects, the utility model provides a kind of delivery roller place circuit card antiseize device that prints can effectively prevent thinner printed circuit board (PCB) clamp in course of conveying, and simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of delivery roller place circuit card antiseize device, some delivery rollers are fixed in the rotating shaft, has the gap between adjacent row's delivery roller, described antiseize device is made of fixed mechanism and support bar, described support bar has relative lower surface and upper surface, the lower surface of described support bar is held in the rotating shaft, the upper surface of described support bar is the plane, described support bar is across at least two rotating shafts, described fixed mechanism is connected at least one end in the rear and front end of described support bar, and described support bar is connected in described rotating shaft by described fixed mechanism.
The utility model is in order to solve its technical matters, and the further technical scheme that adopts is:
Described fixed mechanism is provided with one and be positioned at the front end of described support bar.
Described fixed mechanism is hook, and described hook one is connected in the lower surface of described support bar, and described hook is stuck in described rotating shaft.
Described hook is provided with the lower surface that and one are connected in described support bar front end.
The lower surface of described support bar is the plane.
The upper surface of described support bar and lower surface are the plane that is parallel to each other, and after described antiseize device was installed on rotating shaft, the upper surface of described support bar was level.
After described antiseize device was installed on rotating shaft, the upper surface of described support bar was not higher than the vertex of described delivery roller.
The beneficial effects of the utility model are: antiseize device of the present utility model is made of fixed mechanism and support bar, support bar is connected in rotating shaft by fixed mechanism, the upper surface of support bar is the plane, support bar is across at least two rotating shafts, the utility model is by support bar many adjacent rotating shafts to be overlapped that printed circuit board (PCB) is played a supporting role, and avoids softer printed circuit board (PCB) to fall in the gap between adjacent row's delivery roller and causes clamp.
