[0002] In the field of analytical chemistry, titration analysis is a widely used classical analytical method. Solid sample sampling in chemical titration requires precise weighing. In the past, manual weighing and sampling were used, and the sampling values ​​were recorded manually, which resulted in the problem of human intervention in sampling data. Manual sampling will increase the labor intensity of employees, require additional laboratory staffing, and increase the workload and working time of chemical titration. At the same time, due to human intervention in experimental data, the accuracy of sampling and weighing data will be reduced. Utility Model Content

A glass container is placed in the weighing mechanism. The sample bottle conveyed to the sampling position on the feeding disc is conveyed to the top of the glass container by the manipulator sampling mechanism and the sample is fed into the glass container.

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0017] See Figure 1-Figure 2A fully automatic solid sample sampling machine for chemical titration comprises a conveyor belt 15, a loading disc 28, a manipulator sampling mechanism, and a weighing mechanism. A sample bottle station slot 23 is circumferentially arranged on the loading disc 28. The conveyor belt 15 is arranged on one side of the loading disc 28. When a certain sample bottle station slot 23 on the loading disc 28 rotates to correspond to the conveyor belt 15, the sample bottle 16 on the conveyor belt 15 just enters a certain sample bottle station slot 23 on the loading disc 28 under the action of the dynamic inertia of the conveyor belt 15. A glass container 7 is placed in the weighing mechanism. The sample bottle 16 conveyed to the sampling position on the loading disc 28 is sent to the top of the glass container 7 by the manipulator sampling mechanism and is fed into the glass container 7.

[0018] The manipulator sampling mechanism includes a manipulator horizontal moving module 25, a mechanical claw clamp 6, and a manipulator vertical moving module 1. The manipulator vertical moving module 1 is driven by the manipulator horizontal moving module 25 to move laterally along the direction where the loading disc 29 and the weighing mechanism are set. The mechanical claw clamp 6 is driven by the manipulator vertical moving module 1 to move up and down. The mechanical claw clamp 6 is provided with a mechanical claw rotating motor 4 and a mechanical claw pneumatic clamp 5.

[0019] It also includes a mechanical claw beam 22 and a horizontal module reset sensor 27. The mechanical claw beam 22 is used to connect the mechanical claw clamp 6 and the manipulator vertical movement module 1. The horizontal module reset sensor 27 is set on one side of the manipulator horizontal movement module 25.

[0020] The mechanical claw 6 is connected to the manipulator vertical movement module 1 through the mechanical claw crossbeam 22. The manipulator horizontal movement module 25 and the manipulator vertical movement module 1 are both electric slides. The manipulator vertical movement module 1 moves horizontally on the manipulator horizontal movement module 25. The mechanical claw crossbeam 22 together with the mechanical claw 6 moves up and down on the manipulator vertical movement module 1. The manipulator claw of the utility model is a conventional manipulator claw, wherein the mechanical claw 6 is driven by the mechanical claw pneumatic clamp 5 to achieve clamping, and is driven by the mechanical claw rotary motor 4 to achieve up and down flipping.

[0021] The weighing mechanism is an electronic balance 12, specifically a Mettler electronic balance. The experimental glass container 7 is placed on the electronic balance 12, and the experimental glass container 7 is generally a test conical beaker. The glass container 7 is covered with an electronic balance windshield support 8.

[0022] A material box 32 is provided between the weighing mechanism and the feeding disc 28 .

[0023] The mechanical claw 6 grabs the sample bottle 16 on the feeding disc 28 and transfers it to the sampling position. When it moves to the top of the material box 32, it turns the mouth of the sample bottle 16 downward. Due to the slight vibration generated during the turning, a small amount of powder in the bottle may leak out, which is received by the material box 32 below. The mechanical claw 6 then translates the sample bottle 16 to the top of the test conical beaker. Since the mouth of the sample bottle 16 is very small and the powder has a certain viscosity, there will be no leakage during translation. The mechanical claw rotating motor 4 makes the mechanical claw 6 swing slightly to produce a shaking effect, and the solid powder in the sample bottle 16 is shaken into the test conical beaker little by little. The Mettler electronic balance accurately weighs the solid powder. When the weight is in place, the mechanical claw 6 stops shaking and unloading, completing the sampling.

[0024] The loading disc 28 is driven to rotate by a motor, and a sample arrival sensor 29, a loading disc reset sensor 30, and a sample bottle sampling arrival sensor 9 are arranged on the periphery of the loading disc 28. The sample arrival sensor 29 is arranged on one side of the conveyor belt 15, and the sample bottle sampling arrival sensor 9 is arranged on one side of the weighing mechanism.

[0025] The loading disc reset sensor 30 is used to sense that the loading disc 28 resets to a certain sample bottle station slot 23 and rotates to a position corresponding to the conveyor belt 15. The sample in place sensor 29 is used to sense that the sample bottle 16 on the conveyor belt 15 enters the sample bottle station slot 23. The sample bottle sampling in place sensor 9 is used to sense that the sample bottle 16 rotates to the sampling position of the manipulator.

[0026] It also includes a two-dimensional code scanner 10. A through hole is provided at the bottom of the loading disc 28 at the sampling position, and the two-dimensional code scanner 10 is arranged below the through hole.

[0027] The loading disc 28 is divided into two layers, the upper disc is driven to rotate by a motor, and the upper disc is provided with a plurality of sample bottle station slots 23 along the circumference. When the upper disc rotates to a certain sample bottle station slot 23 corresponding to the conveyor belt 15, the sample bottle 16 on the conveyor belt 15 is pushed into the sample bottle station slot 23 by the power of the transmission belt 15, and the upper disc continues to rotate, driving the sample bottle 16 to rotate to the sampling position. A through hole is provided on the lower disc at the sampling position, and the two-dimensional code scanner scans the information of the sample bottle 16 at the sampling position through the through hole. The outer circumference of the lower disc is provided with an upwardly protruding enclosure 24 to prevent the sample bottle 16 from escaping from the sample bottle station slot 23 during the rotation and movement. The protruding enclosure 24 is provided with an entrance and exit at the position corresponding to the conveyor belt 15.

[0028] The base chassis 14 is used to carry the above equipment and to accommodate, for example, the pneumatic two-way components and solenoid valves for controlling the manipulator gripper, 24V / 10A switching power supply, the manipulator gripper rotation motor driver, the conveyor belt motor driver, the feeding disc motor driver, the manipulator horizontal slide motor driver and the manipulator vertical slide motor driver, and the electronic balance power socket, etc. Two pairs of liftable Foma casters 11 are installed under the base chassis 14, and the side wall surface of the base chassis 14 is sequentially installed with a spare 220V power socket, a main power cord socket, and a gas source jack.
