Abstract
The utility model discloses an anti-adhesion locating supporting lug for ink printing of a printed circuit board. The anti-adhesion locating supporting lug is composed of an upper support and a lower locating pin, wherein the upper support is in a cone shape, the lower locating pin is in a cone shape, the conical tip of the upper support faces upwards, the upper support and the lower locating pin are arranged oppositely, the lower locating pin is integrated formed by extending downwards from the bottom face of the upper support, the conical tip of the lower locating pin is smaller than a locating hole of a base plate on a machine table, the upper end of the lower locating pin is greater than the locating hole of the base plate on the machine table, the conical tip of the lower locating pin is inserted into the locating hole of the base plate, the conical tip of the upper support is smaller than a locating hole of the printed circuit board, the lower end of the upper support is greater than the locating hole of the printed circuit board, and the conical tip of the upper support is inserted into the locating hole of the printed circuit board. While the anti-adhesion locating supporting lug for ink printing of the printed circuit board can elevate and locate the printed circuit board, due to the fact that the upper end of the upper support is the conical tip and is inserted into the printed circuit board, contact between the anti-adhesion locating supporting lug and the printed circuit board is line contact, contact area between the locating supporting lug and the printed circuit board is reduced, and then ink adhesion can be avoided.
Description
Technical field
The utility model belongs to positioner used in manufacturing process for printed circuit board, especially a kind of feet that is used for frame height and positioning printing circuit board when anti-welding printing printing ink.
Background technology
Printed circuit board (PCB) (PCB) is when anti-welding printing printing ink, general first at printing-ink of printed circuit board (PCB), to after the printing ink baking-curing of this one side, printed circuit board (PCB) be overturn, then the printed circuit board (PCB) another side is carried out to ink printing, again by the printing ink baking-curing of this another side, as shown in Figure 1, anti-welding printing printing ink therebetween printed circuit board (PCB) 2 by high backing plate 3 tops that are positioned on board of the high spike of frame (the high PIN of frame) frame, the high spike of tradition frame generally has support cylinder 11 and upper, lower angle 12, 13, support cylinder is high and supporting printing board for frame, support cylinder upper, lower surface is plane, on, lower angle lays respectively at the upper of cylinder, the lower surface middle part, on, lower angle inserts in respectively in the locating hole on printed circuit board (PCB) and backing plate, to play the positioning printing circuit board.Because above-mentioned traditional anti-welding printing ink technique is printed the two sides of printed circuit board (PCB) separately respectively and toasts, with regard to the ink layer that has caused the printed circuit board (PCB) two sides, the inconsistent phenomenons such as aberration appear like this.So, there is the dealer that this anti-welding printing ink flow path is improved, after printed circuit board (PCB) is simultaneously carried out to ink printing, it is the ink printing that turnover panel carries out the printed circuit board (PCB) another side, and then printed circuit board (PCB) is put into to baking box baking-curing is carried out in the two sides of printed circuit board (PCB) simultaneously, though this improved flow process has solved the inconsistent problem in above-mentioned two sides, but there is following defect: due to printed circuit board (PCB), do not dried the ink printing that enters another side after simultaneously printing printing ink, so printed printing ink but not the one side of baking-curing with the upper surface of the high spike of frame, contact, support cylinder upper surface due to the high spike of frame is plane again, large with the contact area of printed circuit board (PCB), easily make printing ink be stained with glutinous, affected the quality of product.
The utility model content
In order to address the above problem, the utility model provides antiseized glutinous positioning support spike for a kind of printed circuit board (PCB) ink printing, printed circuit board (PCB) ink printing of the present utility model with antiseized glutinous positioning support spike at the frame of realizing printed circuit board (PCB) high and the location in, because the contact area of itself and printed circuit board (PCB) is little, also can effectively avoid printing ink to be stained with glutinous, and simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical problem and adopt is:
Antiseized glutinous positioning support spike for a kind of printed circuit board (PCB) ink printing, by upper support and lower alignment pin, formed, described upper support is taper, described lower alignment pin is taper, described upper support cone point upwards, described upper support and described lower alignment pin are oppositely arranged, and from described upper support bottom surface, downward one extension forms described lower alignment pin, the cone point of described lower alignment pin is less than the locating hole of the backing plate on board and the locating hole that upper end is greater than the backing plate on board, the cone point of described lower alignment pin inserts in the locating hole of backing plate, the cone point of described upper support is less than the locating hole of printed circuit board (PCB) and the locating hole that lower end is greater than printed circuit board (PCB), the cone point of described upper support inserts in the locating hole of described printed circuit board (PCB).
The beneficial effects of the utility model are: printed circuit board (PCB) ink printing of the present utility model consists of upper support and lower alignment pin with antiseized glutinous positioning support spike, upper support is taper, lower alignment pin is taper, upper support cone point upwards, upper support and lower alignment pin are oppositely arranged, and from the upper support bottom surface, downward one extension forms lower alignment pin, the cone point of lower alignment pin is less than the locating hole of the backing plate on board and the locating hole that upper end is greater than the backing plate on board, the cone point of lower alignment pin inserts in the locating hole of backing plate, the cone point of upper support is less than the locating hole of printed circuit board (PCB) and the locating hole that lower end is greater than printed circuit board (PCB), the cone point of upper support inserts in the locating hole of printed circuit board (PCB), this antiseized glutinous positioning support spike at the frame of realizing printed circuit board (PCB) high and the location in, due to the upper end of upper support for the cone point and insert in printed circuit board (PCB), making itself and contacting of printed circuit board (PCB) is the line contact, reduced the contact area with printed circuit board (PCB), therefore also can avoid printing ink to be stained with glutinous.
The accompanying drawing explanation
The structural representation that Fig. 1 is prior art;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Embodiment: antiseized glutinous positioning support spike for a kind of printed circuit board (PCB) ink printing, by upper support 4 and lower alignment pin 5, formed, described upper support is taper, described lower alignment pin is taper, described upper support cone point upwards, described upper support and described lower alignment pin are oppositely arranged, and from described upper support bottom surface, downward one extension forms described lower alignment pin, the cone point of described lower alignment pin 5 is less than the locating hole of the backing plate 3 on board and the locating hole that upper end is greater than the backing plate on board, and described lower alignment pin inserts in the locating hole of backing plate, the cone point of described upper support 4 is less than the locating hole of printed circuit board (PCB) 2 and the locating hole that lower end is greater than printed circuit board (PCB), the cone point of described upper support inserts in the locating hole of described printed circuit board (PCB).
