Description

Technical Field

[0001] This utility model relates to the field of safe handling and placement technology, and in particular to a test tube safe handling and placement device for a sample production line. Background Technology

[0002] Automated testing equipment lines are now widely used in various laboratories, providing convenience for quarantine and inspection. In the event of unexpected situations, such as power outages or instrument malfunctions, the automated testing equipment line may stop operating, leaving test tubes containing samples awaiting testing stranded on the line. If the line cannot be restored to operation for an extended period, the test tubes will remain stranded, potentially delaying the detection of test results, affecting subsequent patient care, and possibly leading to inaccurate test results.

[0003] Due to testing requirements, the test tube caps are removed after loading the equipment, leaving the test tubes in a non-sealed state. The production line is a closed space with only a few open windows, making it difficult to remove the test tubes. Current technology uses manual handling to retrieve them.

[0004] Due to the limited space of the instrument window and the limited position of the test tube, manual handling is not only difficult to operate, but may also cause spillage and contamination of the sample to be tested, creating safety hazards. Utility Model Content

Detailed Implementation

[0034] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0035] Example 1

[0036] A specific embodiment of this utility model discloses a test tube safety handling device for a sample processing line, such as... Figure 1 As shown, it includes a clamping unit 1, a connecting unit 2, a control unit 3, and a grip 4. The grip 4 is connected to the clamping unit 1 through the connecting unit 2. The control unit 3 is located between the grip 4 and the connecting unit 2 and is used to control the clamping unit 1 to clamp the test tube.

[0037] The clamping unit 1 includes a connector 11 connected to the connecting unit 2 and a gripper assembly 12. The tilt angle between the gripper assembly 12 and the connecting unit 2 is 70° to 110°, which facilitates the gripper assembly 12 to clamp the test tube from above, increasing the stability of the gripping. The gripper assembly 12 is movably connected to the connector 11, and the control unit 3 can control the gripper assembly 12 to tighten or loosen, thereby completing the picking and placing of the test tube.

[0038] For example, the gripper assembly 12 can be configured as a two-jaw structure or a three-jaw structure.

[0039] In some embodiments, the control unit 3 includes a pressing handle 31 and a brake cable 32. One end of the brake cable 32 is connected to the pressing handle 31, and the other end enters the connector 11 and is connected to the gripper assembly 12. By pressing the pressing handle 31, the brake cable 32 can be pulled to tighten the gripper assembly 12, thereby gripping the test tube.

[0040] The prior art involves pressing the handle 31 to pull the brake cable 32, thereby tightening the clamp assembly 12. For example, bicycles brake by pressing the brake handle to tighten the brake pads and thus brake the bicycle. This will not be elaborated further here.

[0041] Furthermore, such as Figure 2 As shown, a limiting part 21 is provided on the connecting unit 2 to limit the position of the gate cable 32. For example, the limiting part 21 can be a limiting cavity or a limiting groove. The gate cable 32 passes through the limiting cavity or the limiting groove to connect the pressing handle 31 to the gripper assembly 12. By limiting the position of the gate cable 32 through the limiting part 21, the path of the gate cable 32 is fixed, preventing interference with the use of the safety pick-and-place device for the assembly line.

[0042] Preferably, the handle is provided with a grip at 4 points. The grip is made of a skin-friendly and non-slip material, such as rubber, to increase the user's grip comfort and prevent the safety pick-and-place device for the sample production line from falling off.

[0043] Preferably, a friction strip is provided on the side of the gripper assembly 12 that is in contact with the test tube to be gripped. The friction strip is made of an elastic anti-slip material, such as rubber, to increase the stability of the gripper assembly 12 in gripping the test tube and to prevent the gripper assembly 12 from damaging the test tube during the gripping process.

[0044] This utility model, by setting up a clamping unit 1, a connecting unit 2 and a control unit 3, can control the gripper assembly 12 to tighten or loosen through the control unit 3, thereby completing the gripping of test tubes on the production line. It is simple to operate and convenient to use. The gripper assembly 12 clamps the test tube from above, which improves the safety and stability of gripping the test tube and can prevent the spillage and contamination of the sample to be tested inside the test tube.

[0045] Example 2

[0046] A specific embodiment of this utility model discloses a test tube safety handling device for a sample processing line, such as... Figure 3 As shown, the difference from Embodiment 1 is that the connecting unit 2 is set as a telescopic structure, including a fixed rod 22 connected to the clamping unit 1 and a movable rod 23 connected to the gripping rod 4. The fixed rod 22 is a hollow structure, the limiting part 21 is connected to the fixed rod 22, and the movable rod 23 can move along the fixed rod 22, so that the user can easily adjust the length of the connecting unit 2.

[0047] Furthermore, the connecting unit 2 also includes a fixing member 24 for fixing the position of the moving rod 23. In some embodiments, the fixing member 24 can be a fixing pin, and the moving rod 23 is provided with a fixing hole. The fixing member 24 passes through the fixing rod 22 and enters the fixing hole to fix the position of the moving rod 23.

[0048] like Figure 4 As shown, the fixing member 24 can also be a locking block 241 set on the fixing rod 22 and a plurality of elastic locking strips 242 set on the moving rod 23. The locking block 241 cooperates with the elastic locking strips 242 to fix the position of the moving rod 23.

[0049] Furthermore, such as Figure 5 As shown, a wire length control component 321 is provided on the gate wire 32. The wire length control component 321 is located between the fixed rod 22 and the pressing handle 31 and is used to adjust the gate wire 32 according to the length of the connecting unit 2.

[0050] For example, the line length control component 321 can be a BOA knob, which adjusts the length of the gate line 32. The BOA knob is prior art and will not be described in detail here.

[0051] For example, the line length control component 321 can be a cable reel, and the brake line 32 is wound and connected to the cable reel. The length of the brake line 32 wound on the cable reel is adjusted by winding and unwinding the brake line 32.

[0052] The present invention relates to a test tube safety handling device for a sample production line. By setting the connecting unit 2 as a telescopic structure and by setting the line length control component 321, the test tube safety handling device for the sample production line can adjust the clamping length according to the operational needs. It is easy to use and has good adaptability and adjustability.

[0053] Example 3

[0054] A specific embodiment of this utility model discloses a test tube safety handling device for a sample processing line, such as... Figure 6 As shown, the difference from Embodiment 1 or Embodiment 2 is that the clamping unit 1 further includes an adjustment component 13, which is connected to the gripper component 12 and is used to adjust the gripping range of the gripper component 12 so that the gripper component 12 can be adapted to test tubes of different diameters.

[0055] like Figure 7 As shown, the gripper assembly 12 includes a gripping motion component 121 and a gripper 122. The gripping motion component 121 is disposed inside the connector 11 and hinged to the connector 11. The gripper 122 is connected to the gripping motion component 121 through the adjustment component 13. The gate cable 32 is connected to the gripping motion component 121 and can drive the gripping motion component 121 to move, thereby causing the gripper 122 to tighten or loosen, thus completing the picking and placing of the test tube.

[0056] The clamping moving part 121 has an existing structure, such as the tightening structure of bicycle brake pads, which will not be described in detail here.

[0057] Preferably, the gripper 122 is provided with a contact part 1221 made of an elastic material such as silicone or rubber. The contact part 1221 is arc-shaped to facilitate fitting the test tube and improve the stability of gripping the test tube from above.

[0058] In some embodiments, the adjusting component 13 may include a screw 131 and a fixing nut 132. A through hole is provided on the clamping moving part 121. The screw 131 passes through the through hole and is fixedly connected to the jaw 122. The fixing nut 132 is threadedly connected to the screw 131. The position of the screw 131 can be fixed by tightening the fixing nut 132.

[0059] It is understood that by moving the screw 131 along the through hole, the distance between the grippers 122 can be adjusted, thereby adjusting the range of test tube diameters that the gripper assembly 12 can grasp, so that the test tube safety pick-and-place device for the sample production line can be adapted to test tubes of different diameters, improving the stability and adjustability of the gripping.

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
