Description

Technical Field

[0001] This utility model relates to the field of sample reduction technology, specifically to a quantitative reduction device for robotic sample preparation. Background Technology

[0002] Existing sample reduction techniques generally rely on reduction equipment for sample segmentation and sampling. However, this traditional method has a significant problem: sample residue easily remains on the inner walls of the equipment, making thorough cleaning difficult and easily leading to cross-contamination, which in turn affects the accuracy of subsequent experiments or tests. This contamination problem not only increases the workload but may also adversely affect research results or product quality. Summary of the Invention

[0004] To achieve the above and other related objectives, this utility model provides a quantitative reduction device for robot sample preparation, including a hopper device and a reduction gripping device. The hopper device includes a frame, a hopper, a moving plate, and a feeding motor. The hopper is provided on the frame, and a waste collection hopper is provided at the lower end of the hopper. A moving plate is provided between the waste collection hopper and the hopper. A slide rail is provided on the frame, and the moving plate is mounted on the slide rail by a slider. A drive mechanism is provided on the frame to drive the moving plate to move along the slide rail. A sealing cover is provided at the opening at the lower end of the waste collection hopper.

[0005] The shrinking gripper includes a flat plate, shrinking claws, a push-pull cylinder, and a robotic arm. The flat plate is connected to the robotic arm, and the flat plate is equipped with shrinking claws and a push-pull cylinder. The push-pull cylinder is connected to the shrinking claws.

The hopper device includes a frame, a hopper 1, a moving plate 2, and a feeding motor 4. The hopper 1 is mounted on the frame, and a waste collection hopper 10 is mounted at the lower end of the hopper 1. The moving plate 2 is mounted between the waste collection hopper 10 and the hopper 1. The frame is equipped with a slide rail, and the moving plate 2 is mounted on the slide rail by a slider. The frame is equipped with a drive mechanism that drives the moving plate 2 to move along the slide rail. A sealing cover 5 is provided at the opening at the lower end of the waste collection hopper 10.

The flat plate 6 is equipped with the reduction claw 7 and the push-pull cylinder 8. The push-pull cylinder 8 is connected to the reduction claw 7. Through the coordinated work of the robotic arm 9 and the reduction claw 7, the automatic flattening, gripping, and reduction of the sample is realized, which greatly improves the automation level of the reduction process. The flat plate 6 is used to flatten the sample. The reduction claw 7 is located on the flat plate 6 and is used to grip the quantitative sample.

[0026] A vibration motor 3 is provided on one side of the waste collection hopper 10, which helps the sample flow.

[0027] The waste collection hopper 10 is equipped with a feeding motor 4 on one side and a feeding mechanism connected to the feeding motor 4 on the inner side of the waste collection hopper 10. The feeding motor 4 is used to drive the feeding mechanism to ensure that the sample is evenly distributed.

[0028] The sealing cover 5 is symmetrically connected to the left and right sides with sealing cover 5 push-pull cylinders 8. The sealing cover 5 push-pull cylinders 8 are fixed on the frame. The sealing cover 5 is installed at the lower opening of the waste collection hopper.

[0029] The inner side of the reducing claw 7 is rotatably connected to a silicone plate 11. Each time the reducing claw performs a material grabbing and unloading action, the silicone plate will scrape the inner wall of the reducing claw to remove the sample.

[0030] The flat plate 6 and the shrinking claw 7 are integrated into one unit to achieve the functions of flattening and shrinking.

[0031] The working principle of this utility model:

[0032] Sample preparation:

[0033] The sample is poured into hopper 1 through the feed inlet.

[0034] The vibration motor 3 and the feeding motor 4 are started to promote the uniform distribution of the sample in the hopper.

[0035] Flattening and reducing:

[0036] The robotic arm 9 drives the flat plate 6 into the hopper 1 to flatten the sample surface.

[0037] The push-pull cylinder 8 drives the reducing claw 7 to grab a quantitative amount of sample on the front side of the spreading plate 6.

[0038] The reducing claw 7 places the gripped sample into the designated sample container.

[0039] Waste disposal:

[0040] The movable plate 2 retracts, and the remaining sample in the hopper 1 falls into the waste collection hopper 10 through the bottom outlet.

[0041] The sealing cover 5 is controlled by the sealing cover push-pull cylinder 8 to ensure the sealing of the waste collection hopper 10.

[0042] Quantitative sample reduction is achieved by precisely controlling the gripping amount of the reducing claw 7. The use of a robotic arm 9 to drive the reducing claw 7 significantly reduces sample residue on the inner wall of the equipment. The reducing claw 7 has a simple structure, and any remaining sample is easy to remove, avoiding secondary contamination. The entire reduction process is controlled by the robotic arm 9, enabling automatic sample leveling, gripping, and unloading. The coordinated use of the sealing cap 5 and the sealing cap push-pull cylinder 8 effectively prevents the leakage of dust and other harmful substances, ensuring a clean and safe operating environment.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model.
