Embodiment
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing to Automatic pathological specimen recognizer of the present invention.
Embodiment one: as shown in figs 1 to 6, Automatic pathological specimen recognizer of the present invention, form primarily of base 15, line slideway auxiliary 12, rectilinear movement platform 16, pathological specimen embedding box 18, support 19, label data harvester 21, control circuit, power supply and microcomputer 22, label data harvester 21 is generally camera or camera or bar code scan equipment, and microcomputer 22 is single-chip microcomputer or PLC or computer.Line slideway auxiliary 12 is arranged on base 15, pathological specimen embedding box 18 is located on rectilinear movement platform 16, can be fixed by fixture 17, rectilinear movement platform 16 is seated on line slideway auxiliary 12, can to be with by gear/gear shape or the gear train such as gear/rack adds minisize dc servomotor or driving stepper motor, when rotating done by motor, pathological specimen embedding box can be made to import fixture 17, and linearly guideway 12 is reciprocating, thus pathological specimen embedding box 18 placed on it is also moved thereupon.Label data harvester 21 to be arranged on support 19 and the top being positioned at line slideway auxiliary 12 for gathering the encode identification information of pathological specimen embedding box 18.Line slideway auxiliary 12 is provided with the photoelectric detection switch 11 for detecting pathological specimen embedding box 18 shift position and photoelectric detection switch 14, and control circuit controls the position of rectilinear movement platform 16 by photoelectric detection switch 11 and photoelectric detection switch 14.In order to the encode identification information of pathological specimen embedding box 18 reliably can be read, the de-waxing apparatus 23 that the paraffin covered on the code identification face of pathological specimen embedding box 18 is removed is provided with above line slideway auxiliary 12 end, comprise heat gun 1 and micro air pump 3, heat gun 1 is arranged on the top of line slideway auxiliary 12, be connected with micro air pump 3 by conduit 2, when pathological specimen embedding box 18 moves to below heat gun 1, the melted paraffin wax on pathological specimen embedding box 18 code identification face can be removed by thermal current that nozzle 20 on heat gun 1 sprays.The thermal current ejected in order to avoid heat gun 1 is directly injected to the damage parts such as line slideway causing these parts, de-waxing apparatus 23 also can comprise exhaust duct 4 and a fan 6, one of exhaust duct 4 rectifies the removing position to pathological specimen embedding box 18, the other end of exhaust duct 4 is provided with exhaust fan 6, in order to promote effect further, de-waxing apparatus 23 also can arrange a displacement guide rail pair 7, one thermal current gatherer 8 and a back-moving spring 10, thermal current gatherer 8 can be arranged on the slide block 9 of displacement guide rail pair 7 movably forward and backward, one end of exhaust duct 4 is positioned at thermal current gatherer 8, back-moving spring 10 one end is fixed in frame, the other end is fixed on thermal current gatherer 8.Implement paraffin layer 37 remove if pathological specimen embedding box 18 needs to enter de-waxing apparatus 23, under the thrust of fixture 17, thermal current gatherer 8 moves along guideway 7 and is inserted in exhaust duct 4(sees Fig. 5, Fig. 6).When fixture 17 leaves cleaning machine 23, because its thrust disappears, under the acting force of back-moving spring 10, thermal current gatherer 8 resets, and can continue to collect thermal current to make thermal current gatherer 8.
Principle of work is as follows: need the pathological specimen embedding box 18 identified to be placed on (see figure 1) in fixture 17; Pathologic specimen recognizer is started from microcomputer 22; The electric current that control circuit exports makes the drive motor of rectilinear movement platform 16 rotate and pathological specimen embedding box 18 is moved to (see figure 3) immediately below camera 21; Now photoelectric detection switch 11 provides signal, and control circuit makes motor stop and starting the code identification image that pathological specimen embedding box 18 taken by camera 21; View data processes through microcomputer 22, if successfully read the code identification of pathological specimen embedding box 18, microcomputer 22 sends pathological specimen embedding box link order and exports pathological specimen embedding box data encoding, make rectilinear movement platform 16 that pathological specimen embedding box 18 is retracted into reference position, identifying terminates.If sense data failure, microcomputer 22 sends instruction and pathological specimen embedding box 18 is moved in de-waxing apparatus 23 by rectilinear movement platform 16 carry out removing (see figure 5) to paraffin layer 37.The process removed is as follows: micro air pump 3 turns to high-pressure air feed from low pressure air feed under the driving of control circuit, and heat gun 1 also transfers high heating power to from low heating power; Now nozzle 20 ejects suitable thermal current; Pathological specimen embedding box 18 moves with a fixed speed under the driving of rectilinear movement platform 16; When the code identification face of pathological specimen embedding box 18 enters into the thermal current region of nozzle 20 injection, the paraffin layer 37 covered on pathological specimen embedding box 18 code identification face melts and blow off (see Fig. 5, Fig. 6) rapidly by thermal current.After pathological specimen embedding box 18 moves to the terminal of line slideway auxiliary 12, control circuit orders about the counter motion of rectilinear movement platform 16, pathological specimen embedding box 18 is made to exit de-waxing apparatus 23 and the below turning back to camera 21 is taken again, if data successfully read, microcomputer 22 exports identification data and sends instruction and pathological specimen embedding box 18 is retracted into reference position, and identifying terminates.Otherwise can again enter paraffin removal program until successful sense data.
Embodiment two: as shown in figs. 7 to 9, the Automatic pathological specimen recognizer of the present embodiment, its agent structure is identical with embodiment one, difference is the structure of de-waxing apparatus 23, what embodiment one adopted is the paraffin layer that cordless (by thermojet air-flow) removes pathological specimen embedding box code identification face, and the present embodiment then adopts the way of contact to remove the paraffin layer in pathological specimen embedding box code identification face.De-waxing apparatus 23 forms primarily of bearing seat 35, bearing 31, roller 30, sheath 33 and electrical heating elements 34, roller 30 is installed in rotation on a fixed mount 32 by bearing 31, bearing seat 35, fixed mount 32 is positioned at the side of line slideway auxiliary 12, and roller 30 contacts with the paraffin layer 37 at the code identification face place of pathological specimen embedding box 18 and coordinates.Be cavity structure in the middle part of roller 30, sheath 33 is fixed on bearing seat 35 end and extends in the central cavity of roller 30, and electrical heating elements 34 is located at pair roller 30 in sheath 33 and is heated.In the bottom of fixture 17, spring 36 is also installed, makes code identification face and roller 30 reliable contacts of pathological specimen embedding box 18, play the effect improving paraffin layer 37 elimination effect.
Principle of work is as follows: when roller 30 rotates around axle center, and electrical heating elements 34 and sheath 33 thereof do not rotate with it.After electrical heating elements 34 is energized, can pair roller 30 heat and the temperature on roller 30 surface is increased to can the temperature of melted paraffin rapidly; When pathological specimen embedding box 18 moves into contact de-waxing apparatus 23 under the effect of the platform 16 that moves linearly, the code identification face of pathological specimen embedding box 18 contacts with roller 30 (see figure 9), and the paraffin layer 37 on pathological specimen embedding box 18 code identification face touches roller 30 and melted rapidly; When pathological specimen embedding box 18 does translation motion, drive roller 30 to rotate, until pathological specimen embedding box 18 leaves roller 30, complete a paraffin layer reset procedure.
