Needle blade face positioning device

The utility model relates to a needle blade face positioning device which comprises a linear vibrator and a clamping groove plate fixedly connected with the top end of the linear vibrator, a clamping groove is formed in the clamping groove plate, and a needle positioning plate and an assembling groove are arranged at the first end of the clamping groove. The soft linear vibrator is adopted as a driving device, the width of the clamping groove is equal to the thickness of the needle tube, the needle tube cannot move left and right and can only rotate front and back while the freedom degree of the needle tube is ensured, the needle tip is effectively protected, and the rejection rate of products is greatly reduced; besides, the assembling groove enables the manipulator to accurately carry the needle tube, direct assembling of the needle base is facilitated, and the problem that the needle blade face shifts in the needle base assembling process is avoided. 本实用新型为针刃面定位装置，包括直线振动器和与直线振动器顶端固定连接的卡槽板，卡槽板上设有卡槽，卡槽的第一端设有
