Description

Technical Field

[0001] This utility model relates to the field of reagent tube cutting equipment technology, and in particular to an automatic reagent tube cutting device. Background Technology

[0002] Test tubes are commonly used instruments in experiments across various fields, serving as reaction containers for small amounts of reagents. There are various types of test tubes, including ordinary test tubes, side-braced test tubes, and centrifuge tubes.

[0003] To obtain different types of test tubes, a cutting device is generally used to cut them during processing. Currently, most of the cutting equipment used is machine tool cutting equipment. This type of cutting equipment is more industrialized, has a larger size, and is not suitable for the cutting needs of laboratory and other occasions. The cost of using machine tool cutting equipment is also relatively high. In addition, after the current cutting equipment cuts the reagent tubes, manual breaking is still required, which is not only time-consuming and labor-intensive, but also poses safety hazards such as injury to fingers.

[0004] In view of the above problems, we designed a cutting device that is not only relatively low in cost but also suitable for cutting reagent tubes in laboratory settings. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an automatic reagent tube cutting device. The designed cutting device consists of three parts: a positioning and clamping component, a cutting component, and a detachment component. It has a simple structure, low cost, and small overall size, making it suitable for cutting reagent tubes in laboratory settings. The detachment component enables the upper half of the reagent tube, which has been cut by the cutting blade, to break off from the cut and detach from the lower half, eliminating the need for manual breaking. It is convenient and safe to use.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An automatic reagent tube cutting device is characterized by comprising a fixed base plate, a positioning and clamping assembly, a cutting assembly, and a disengagement assembly. The positioning and clamping assembly is installed at the center of the fixed base plate, and the cutting assembly and the disengagement assembly are respectively installed on the sides of the positioning and clamping assembly.

[0008] The positioning and clamping assembly consists of a rotary gripper finger cylinder, a clamping plate, and a positioning sleeve. The rotary gripper finger cylinder is mounted on a fixed base plate. A gripper portion is mounted on the rotating part of the rotary gripper finger cylinder. The rotation of this gripper portion and the clamping and releasing of the gripper portion are controlled by the rotary gripper finger cylinder. The gripper portion of the rotary gripper finger cylinder is connected to the clamping plate. A positioning sleeve is installed above the rotating part of the rotary gripper finger cylinder.

[0009] The cutting assembly consists of a finger cylinder, a mounting plate, and a cutting blade. The finger cylinder is fixedly mounted on a first support plate, and its two pneumatic grippers are respectively connected to the mounting plate. The cutting blade is mounted on the inner side of the mounting plate.

[0010] The detachment assembly includes a telescopic cylinder, a mounting base, and an impact part. The telescopic cylinder is fixedly mounted on the second support plate via the mounting base, and the telescopic end of the telescopic cylinder is connected to the impact part.

[0011] Furthermore, a reagent tube is placed inside the positioning sleeve.

[0012] Specifically, the first support plate is installed on the top of the first support rod, and the bottom of the first support rod is fixed to the fixed base plate.

[0013] Specifically, the second support plate is installed on the top of the second support rod, and the bottom of the second support rod is fixed to the fixed base plate.

[0014] The beneficial effects of this utility model are:

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1

[0024] As shown in the figure, a positioning and clamping assembly is installed at the middle position on the fixed base plate 11. The rotary gripper finger cylinder 12 in the positioning and clamping assembly is installed on the fixed base plate 11. The rotary gripper finger cylinder 12 uses existing commercially available equipment. The rotary gripper finger cylinder 12 is a pneumatic actuator that combines linear motion and rotary motion functions. It is used to clamp and rotate workpieces. Its working principle can be divided into two core parts: clamping and rotation. The clamping part uses pneumatic drive to control the opening and closing of the gripper part 18 to complete clamping and releasing. The rotation part can be implemented by using a gear rack and pinion structure and a spiral groove structure or by using an independent rotary cylinder to control the rotation of the gripper part 18 in steps.

[0025] The gripper part 18 of the rotary gripper finger cylinder 12 is connected to the clamping plate 17, and a positioning sleeve 4 is installed above the rotating part 17 of the rotary gripper finger cylinder 12. The positioning sleeve 4 is used to place the reagent tube 5.

[0026] A cutting component and a detachment component are provided on the side of the positioning and clamping assembly. The cutting component consists of a finger cylinder 15, a mounting plate 2, and a cutting blade 6. The finger cylinder 15 is fixedly mounted on the first support plate 1. The first support plate 1 is mounted on the top of the first support rod 13. The bottom of the first support rod 13 is fixed on the fixed base plate 11. The two pneumatic grippers 3 of the finger cylinder 15 are respectively connected to the mounting plate 2. The cutting blade 6 is mounted on the inner side of the mounting plate 2. The finger cylinder 15 uses an existing commercially available pneumatic component. Its principle is to realize the clamping function of the pneumatic grippers 3 through the action of two pistons.

[0027] The detachment assembly includes a telescopic cylinder 16, a mounting base 8, and an impact part 14. The telescopic cylinder 16 is fixedly mounted on the second support plate 9 via the mounting base 8. The second support plate 9 is mounted on the top of the second support rod 10, and the bottom of the second support rod 10 is fixed on the fixed base plate 11. The telescopic end of the telescopic cylinder 16 is connected to the impact part 14.

[0028] Example 2

[0029] When using this utility model, the reagent tube 5 is placed in the positioning sleeve 4. The rotating gripper finger cylinder 12 first drives the gripper part 18 to drive the clamping plate 7 to clamp the reagent tube 5. Then, it drives the rotating part 17 to drive the reagent tube 5 to rotate forward, reverse, or rotate in both directions a certain number of times. At the same time, after the reagent tube 5 is clamped by the clamping plate 7, the finger cylinder 15 drives the gripper 3 to move the mounting plates 2 on both sides toward the reagent tube 5. The cutting blade 6 mounted on the mounting plate 2 is pressed against the outer wall of the reagent tube 5. The rotating part 17 of the rotating gripper finger cylinder 12 drives the reagent tube 5 to rotate to complete the cutting of the reagent tube 5.

[0030] After the cutting is completed, the rotating part 17 of the rotating gripper finger cylinder 12 stops rotating, and the telescopic cylinder 16 drives the impact part 14 to extend forward and impact the reagent tube 5, so that the upper half of the reagent tube 5 is cut by the cutting blade 6 and breaks off from the cut and separates from the lower half. At this time, the cutting of the reagent tube 5 is completed. The telescopic cylinder 16 controls the impact part 14 to retract, and the cutting blade 6 and the clamping plate 7 are all released and reset, and the cut reagent tube 5 can be taken away from the positioning sleeve 4.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
