Liam Feeney enjoyed the best chance of a stop-start first period which was disrupted by torrential rain when he raced away from Damien McCrory but was twice denied by goalkeeper Tony Roberts.
The game came to life after 48 minutes when Jon Nurse peeled away from his marker to nod in a deep free-kick from Danny Green to put the home side in front.
However, going behind simply woke Bournemouth up and the introduction of Danny Ings breathed fresh life into their game. Within moments of coming on, the substitute headed in Adam Smith’s cross only to see his attempt ruled out for a marginal offside.
Yet he was not to be denied a minute later, though, as the Cherries broke in numbers and Marc Pugh’s pin-point cross gave Ings the simple task of heading in at the back post.
Both sides brought on substitutes in search of a winner but it was Robinson, reacting quickest to a Steve Fletcher knockdown, who had the final say.
