The specific embodiment
Below in conjunction with embodiment, the invention will be further described:
Fig. 1 is one embodiment of the present of invention structural representation.A kind of chute for arraying infusion needles, it contains the workbench 1 that is skewed, workbench surface is provided with and is some syringe needle chutes 2 of arranging shape, workbench bottom is provided with bobbing machine 3, described in be on skewed workbench, be also provided with proofread and correct guide pad 4, queue up seat 5, baffle plate 6 and transverse-moving mechanism 7.The syringe needle that has processed needle point falls from chute with the form of syringe needle afterbody, avoids from the beginning syringe needle impaired.Fig. 2 is that Fig. 1 embodiment proofreaies and correct guide pad schematic diagram.Described correction guide pad upper surface is comprised of flat face 41, groove 42, boss 43, described boss is provided with the correction chute 431 corresponding with aforementioned some syringe needle chutes, flat face is transitioned into trench bottom surfaces by inclined-plane 411, proofread and correct chute bottom land and trench bottom surfaces at grade, described correction guide pad is close to and is fixed on aforementioned workbench front end face, and its flat face docks with aforementioned some syringe needle chute bottom lands.Described inclined-plane can be cancave cambered surface, flat face and cambered surface rounding off, and cambered surface end forms a step higher than trench bottom, as shown in Figure 2.Described inclined-plane can be a cancave cambered surface, and cancave cambered surface is connected flat face and trench bottom surfaces, as shown in Figure 3.Described inclined-plane can be also S shape cambered surface, and S shape cambered surface is connected flat face and trench bottom surfaces, as shown in Figure 4.Proofread and correct the flat face of guide pad adopt cancave cambered surface to be mainly with the interface of trench bottom because: when syringe needle is during with the form downslide of afterbody, vibration due to bobbing machine, syringe needle can successfully glide, when needle point starts to streak cancave cambered surface, because the tangent slope of cancave cambered surface each point is greater than the inclination angle of needle point, and now syringe needle afterbody is positioned at chute groove bottom, needle body soars, as shown in enlarged drawing 2.If syringe needle, when non-equilibrium site, due to the effect of gravity, forces syringe needle cast-over point to rotate, cancave cambered surface provides the space of rotating, and over against chute inclined-plane, has found thus the inclined-plane of needle point accurately position that syringe needle is arranged.Cancave cambered surface end shown in Fig. 2 forms a step 511 higher than trench bottom, makes the inclined-plane of needle point rest on step, more easily finds the correct position of needle point accurately.Fig. 3 has provided cancave cambered surface and has been connected flat face and trench bottom surfaces enlarged diagram, equally also can obtain satisfied effect.Fig. 4 has provided the schematic diagram of S shape cambered surface linking flat face and trench bottom surfaces, and the arc of second half section can alleviate the impulsive force that needle point glides.
The outside of described correction guide pad is provided with the seat of queuing up, described queuing seat is by pedestal 5, rotating shaft 52, baffle plate 6, jib 54 forms, pedestal upper surface has pedestal groove 511 along its length, the both sides of groove are provided with the queuing chute 512 corresponding with aforementioned some correction chutes, queuing chute bottom surface and pedestal groove bottom are at grade, pedestal is positioned on the platform of rotating shaft top, pedestal one side is alignd with platform to be fitted in and is proofreaied and correct guide pad outside, described correction chute bottom and queuing chute bottom are on same straight line, the opposite side of rotating shaft platform is established rail groove 513, baffle plate is positioned on rail groove and seals bottom queuing chute, described baffle plate can move left and right along rail groove, rotating shaft is fixed on jib by bearing, jib is fixed on aforementioned workbench two sides.When the present invention works, when the syringe needle of uniform marshalling enters queuing chute, because being positioned at, baffle plate on rail groove, seals queuing chute bottom, baffle plate plays the role of positioning, if baffle plate is connected with transverse-moving mechanism reciprocating air cylinder, baffle plate is along the rotating shaft one quick traversing position that can further adjust needle tip inclined-plane, rail groove left and right.Now another T-shaped is pressed in and is queued up in seat pedestal groove, the syringe needle of adjusting to the right place is fixed, then rotated by actuating unit drive shaft, the seat of queuing up is with to proofread and correct guide pad separated and rotate, and needle head body is horizontal be convenient to the gripping of mechanical hand.
The syringe needle needle point tip of sliding in this chute is subject to any impulsive force, therefore needle point can not sustain damage.
Above-described embodiment is not construed as limiting the invention, and all employings are equal to replaces or technical scheme that the form of equivalent transformation obtains, within all dropping on protection scope of the present invention.
