A test tube handling system for individual handling as shown in fig. 1, comprising a holding device, a transmission device and a taking device; the transmission device comprises a control box 32, a transmission rod 33, a forward and reverse rotation motor 31 and a time relay 34, wherein the time relay 34 is in circuit connection with the forward and reverse rotation motor 31, an output shaft of the forward and reverse rotation motor 31 is connected with an input shaft of the control box 32 in a driving mode, an output shaft of the control box 32 is the transmission rod 33, and a gear structure arranged at the far end of the transmission rod 33 is meshed with a lower-section gear of the driving rod 16 in the clamping device; the driving rod 16 in the clamping device is of an upper, middle and lower three-section structure, the upper section is a lead screw, a nut of the lead screw is sleeved in a horizontal gear of the operating wheel set 22, a gear is horizontally arranged on the lower section rod and is meshed with a gear at the end part of the transmission rod 33, the middle section and the upper section are connected through a sleeve bearing, and the middle section and the lower section are connected through a reverse gear set 14; the flat-taking device is arranged right above the clamping device.
The clamping device comprises a cylindrical test tube table 1, an arc block-shaped movable block 11, an arc block-shaped fixed block 12, a driving rod 16 connected to the bottom of the test tube table 1 and a bent rod-shaped driven rod 13; a circle of circular sliding grooves are formed in the upper surface of the test tube platform 1, the depth of each sliding groove is smaller than the thickness of the test tube platform 1, the number of the movable blocks 11 is two, the number of the fixed blocks 12 is one, the movable blocks 11 and the fixed blocks 12 can be vertically inserted into the sliding grooves in a horizontally moving mode, and through grooves are formed in the bottom surfaces of the sliding grooves; the bottom of the movable block 11 is connected with a passive rod 13, the top end of a driving rod 16 is connected to the bottom of the test tube platform 1, and the other ends of the two passive rods 13 are respectively connected to the middle section and the lower section of the driving rod 16 which are vertically arranged; the vertical part of the passive rod 13 is provided with a sleeve structure, so that the top end of the passive rod 13 can move up and down without influencing the rotation or movement of the passive rod in the horizontal direction.
The leveling device comprises a clamping ring 41, a moving block 42, a support rod 43 and a cross beam rod 45; the clamping rings 41 are arc-shaped semi-rings with an angle smaller than 150 degrees, the number of the clamping rings is two, and the two clamping rings 41 are horizontally arranged oppositely; the moving block 42 is arranged in the middle of one end part of the two clamping rings 41 and is connected with the near ends of the two clamping rings 41; the supporting rod 43 is vertically arranged, the moving block 42 is movably fixed at the bottom of the supporting rod 43, and the movable direction of the moving block 42 is vertical to the radial direction of the supporting rod 43; one end of the clamping ring 41 close to the moving block 42 is a rotating wheel, two sides of the moving block 42, which are in contact with the clamping ring 41, are of a fixed tooth structure, and the rotating wheel is meshed with the fixed teeth; the top of the supporting rod 43 is an inward bending structure, and a pulley 44 in the bending structure is arranged on a beam rod 45, so that the supporting rod 43 can translate along the beam rod 45.
The operating wheel set 22 further has a vertical gear engaged with the horizontal gear, and an operating rod 21 passing through the vertical gear is disposed perpendicular to the driving rod 16.
When the test tube taking clamp is used, the moving block 42 is aligned with a test tube to be taken, the operating rod 21 is rotated to enable the upper section of the driving rod 16 to move upwards due to the movement of the operating wheel set, so that the test tube table 1 is lifted upwards independently of other test tubes, then the supporting rod 43 is slid to the position of the test tube, the test tube pushes the moving block 42 to approach the supporting rod 43, the clamping ring 41 is clamped through the meshing structure of the rotating wheel and the fixed gear, the forward and reverse rotating motor 31 is started within a certain time through the circuit control time relay 34, the forward and reverse rotating motor 31 is made to rotate the transmission rod 33 corresponding to the test tube to be taken through the control box 32, so that the two moving blocks 11 are finally closed to the fixed block 12 from two sides through the transmission structure of the driving rod 16, the driven rod 13 and the reverse gear set 14, and then the supporting rod 43 is continuously translated to clamp.
In the above arrangement, the time relay 34 is mainly used to control the running time of the forward and reverse rotation motor 31, so that the movable block 11 stops at a position just moving close to the fixed block 12, or stops at a position far away from the fixed block 12 where the movable block 11 moves to clamp the test tube. It is clear that the use of a forward and reverse asynchronous motor 31 facilitates the relative movement of the movable block 21. Meanwhile, since in actual use, one forward and reverse asynchronous motor 31 may need to operate a plurality of transmission rods 33, the control box 32 is adopted to perform selective operation on the transmission rods 33 needing to be operated.
In order to increase the force bearing area of the bottom of the test tube, the upper surface of the test tube platform 1 is in a downward concave arc shape at the part surrounded by the sliding groove.
For the same purpose, the moving block 42 is further horizontally curved relative to the distal side of the supporting rod 43.
The reversing gear set 14 is also fixed in an auxiliary manner through a fixing rod 15 which is horizontally arranged, and the fixing rod 15 penetrates through a bearing in the middle of a gear in the reversing gear set 14; the reverse gear set 14 is configured to rotate in the up-down direction. The relative movement of the two movable blocks 21 is thus achieved mechanically and no abnormal situation occurs due to the movement of the gears of the intermediate transmission.
The number of the rotating wheels is at least one on each clamping ring 41; the width of the fixed teeth is larger than or equal to that of the rotating wheel. Thereby ensuring a coupling effect between the clamp ring 41 and the moving block 42.
