[0047] By placing the material bottle on the weighing platform of the weighing device 2, the material ratio state in the material bottle can be observed in real time. By using the grasping mechanism to grasp and drive the first fitting 5 provided with the burette 6 or the micropipette 7 to move, the cooperation of the burette 6 and the micropipette 7 can be used to achieve the precise filling of the liquid material in the material bottle.

[0053] Through the cooperation of the first electric slide rail 11, the second electric slide rail 12 and the third electric slide rail 13, the third mounting bracket 14 can realize three-axis sliding in XYZ directions.

[0054] Furthermore, an electric gripper (not shown in the figure) is also slidably matched on the third electric slide rail 13. The electric gripper is used for clamping and transferring the material bottle.

[0055] In an embodiment of the present invention, the clamping member includes a first magnetic attraction member 15 and a second magnetic attraction member 16 respectively facing the first mounting bracket 4 and the second mounting bracket 8;

[0056] A first magnet for connecting with the first magnetic attraction member 15 is arranged on the first fitting 5, and a second magnet 91 for connecting with the second magnetic attraction member 16 is arranged on the second fitting 9.

[0057] The grasping of the first fitting 5 and the second fitting 9 can be achieved through the engaging cooperation between the first magnetic attracting member 15 and the first magnet and the engaging cooperation between the second magnetic attracting member 16 and the second magnet 91.

[0058] Furthermore, the first magnetic attracting member 15 and the second magnetic attracting member 16 can be ordinary magnets or electromagnets.

[0059] In an embodiment of the present invention, a first card slot is formed at one end of the first fitting 5 close to the first mounting bracket 4, and a first card block for engaging and supporting with the first card slot is fixedly connected to the first mounting bracket 4.

[0060] The opening of the first card slot faces downward, and the cooperation between the first card slot and the first card block enables the first fitting 5 to be inserted into the first mounting bracket 4.

[0061] In an embodiment of the present invention, a second card slot 92 is formed at one end of the second fitting 9 close to the second mounting bracket 8, and a second card block 93 for engaging and supporting with the second card slot 92 is fixedly connected to the second mounting bracket 8.

[0062] The opening of the second card slot 92 faces downward, and the cooperation between the second card slot 92 and the second card block 93 enables the second fitting 9 to be inserted into the first mounting bracket 4.

[0063] In an embodiment of the present invention, the magazine 10 is successively provided with a driving chamber and a material chamber from top to bottom. An outlet 104 is provided at the bottom end of the material chamber. An elastic reset mechanism is slidably and rotatably arranged in the driving chamber. The elastic reset mechanism is fixedly connected with a powder feeding rod 105. The powder feeding rod 105 extends into the material chamber and protrudes through the outlet 104. A material groove 106 is formed on the side wall of the powder feeding rod 105. The elastic reset mechanism is fixedly connected with a stirring member located in the material chamber. The magazine 10 is detachably connected with a storage bottle 103 communicated with the material chamber. The elastic reset mechanism includes a rotating seat 107 rotatably connected in the driving chamber through a bearing; a slider 101 is slidably connected in the rotating seat 107, and the slider 101 is fixedly connected with the powder feeding rod 105; an elastic member 102 is arranged between the slider 101 and the rotating seat 107.

[0064] When the powder feeding rod 105 is inside the material bin, the material can be located in the material trough 106. By pressing down the slider 101 to drive the powder feeding rod 105 to move synchronously, after the material trough 106 extends out of the material bin, the material in the material trough 106 can fall out of the material bin 10. On the contrary, the elastic member 102 can make the slider 101 and the powder feeding rod 105 automatically reset, so that the powder feeding rod 105 automatically retracts into the material bin. In this way, pushing the powder feeding rod 105 multiple times can achieve precise discharging. And when pushing the slider 101, rotating the slider 101 synchronously can drive the rotating seat 107 to rotate synchronously. The rotating seat drives the stirring member to make the material descend, which is convenient for the material trough 106 to contact the material. And the stirring member can also stir the solid powder to prevent the solid powder from caking.

[0065] In an embodiment of the present invention, a telescopic member 17 is provided on the grasping mechanism. The output end of the telescopic member 17 is rotatably connected with a third clamping block 19 through a driving member 18. A third clamping groove 20 for engaging with the third clamping block 19 is opened at the top end of the slider 101.

[0066] The third clamping block 19 and the third clamping groove 20 are of a cross structure. The telescopic member 17 is a cylinder for pushing the powder feeding rod 105, and the driving member 18 is a motor for driving the powder feeding rod 105 to rotate.

[0067] Furthermore, the material trough 106 is spiral, which is convenient for the solid powder material in the material trough 106 to automatically fall out of the material trough 106.

[0068] Furthermore, the elastic member 102 is a spiral spring.

[0069] Furthermore, a plurality of sliding grooves 108 are opened on the inner side wall of the rotating seat 107. A connecting block 109 is slidably fitted in the sliding grooves 108, and the connecting block 109 is fixedly connected with the slider 101.

[0070] By providing the sliding grooves 108 and the connecting blocks 109 slidably fitted with the sliding grooves 108, when the slider 101 rotates, it can drive the rotating seat 107 to rotate synchronously through the connecting blocks 109. And when the slider 101 slides, the connecting blocks 109 slide in the sliding grooves 108, achieving the effect of driving the powder feeding rod 105 to extend and retract and driving the stirring member to rotate only by driving the slider 101.

[0071] Furthermore, the stirring member includes a sleeve 110 and spiral blades 111 arranged on the outer side wall of the sleeve 110. The sleeve 110 is fixedly connected with the rotating seat 107, and the sleeve 110 is sleeved outside the powder feeding rod 105.

[0072] In an embodiment of the present invention, it further includes a number of large liquid storage tanks 21 storing different liquids. The number of large liquid storage tanks 21 is connected to a number of titrators 6, so that different titrators 6 can output different liquids. The titrator 6 is connected to the large liquid storage tank 21 through a flexible hose.

[0073] In an embodiment of the present invention, it further includes a reagent rack 22 provided with a number of grooves. The reagent rack 22 is within the operation range of the grasping mechanism. Different specifications of pipette tips for a small-range pipette 7 and small liquid storage tanks storing different liquids are placed in the number of grooves.

[0074] Pipette tips of different specifications are suitable for different liquid ratios, and the small liquid storage tanks are used to store small amounts of liquid.
