Description

Technical Field

[0001] This utility model relates to the field of sample storage technology, and in particular to a tube transfer device. Background Technology

[0002] In biological sample storage devices, manual or robotic arms are typically used for tube picking and transfer operations. However, conventional laboratories still use single-tube transfer clamps, which is inefficient.

Generally, when conducting experiments with small batches of sample tubes, semi-automatic sample tube gripping mechanisms are more efficient than fully automatic ones.

[0004] In summary, a tube transfer device is invented that can achieve semi-automatic grasping or placement of sample tubes. Utility Model Content

[0035] Preferably, the elastic clamping component 2 can clamp multiple groups of sample tubes 9 at the same time, or it can clamp a single group of sample tubes 9.

[0036] In summary, the elastic clamping component 2, with its elasticity, can easily clamp multiple sample tubes, facilitating transfer and improving the efficiency of sample tube extraction.

[0037] Example 2

[0038] Reference Figures 1-4 This is the second embodiment of the present invention. In the previous embodiment, the tube transfer device includes a housing mechanism 1 and an elastic clamping component 2. The housing mechanism 1 is provided with the elastic clamping component 2, which can clamp multiple sets of sample tubes.

[0039] Specifically, it includes a housing mechanism 1 and an elastic clamping component 2; the housing mechanism 1 is provided with an elastic clamping component 2, which can clamp multiple sets of sample tubes 9 at the same time.

[0041] Furthermore, it also includes a telescopic pressing mechanism 3, which is installed on the housing mechanism 1. Multiple sample tubes 9 on the elastic clamping assembly 2 are pressed and disengaged by the telescopic pressing mechanism 3.

[0042] Preferably, the telescopic pressing mechanism 3 can push the sample tube held by the elastic clamping component 2 by moving and lifting, thereby placing multiple sets of sample tubes. When the telescopic pressing mechanism 3 has finished pushing multiple sets of sample tubes, it can automatically reset.

[0043] Furthermore, the elastic clamping assembly 2 includes a fixing member 21 and an elastic member 22; the elastic member 22 is provided on one side of the fixing member 21, and multiple sets of fixing members 21 and elastic members 22 are provided. The fixing member 21 and the elastic member 22 can cooperate to clamp the sample tube 9, and the elastic member 22 can elastically deform to guide and clamp the sample tube 9.

[0044] Preferably, the fixing member 21 includes a cylindrical pin, which can cooperate with the elastic member 22 to clamp and fix the sample tube 9.

[0045] Preferably, the elastic element 22 has a certain degree of elasticity and can be squeezed into the sample tube between the fixing element 21 and the elastic element 22.

[0046] Furthermore, the elastic member 22 includes a guide portion 221 and a clamping portion 222; the lower end of the clamping portion 222 is provided with the guide portion 221, which can guide the sample tube 9, and the clamping portion 222 and the fixing member 21 can clamp and fix the sample tube 9.

[0047] Preferably, the guide section 221 can guide the sample tube so that it can be accurately inserted into the slot.

[0048] Preferably, the sample tube can be firmly clamped by the clamping part 222 and the fixing member 21.

[0052] Furthermore, the telescopic pressing mechanism 3 includes a pressing component 31, which is disposed inside the housing mechanism 1. The pressing component 31 can move to press the multiple sets of sample tubes 9 on the elastic clamping component 2, and can cause the multiple sets of sample tubes 9 to disengage from the elastic clamping component 2.

[0053] Preferably, the pressing component 31 can press the sample tubes in the clamp, causing multiple sets of sample tubes in the clamp to simultaneously detach from the elastic clamping component 2, thus completing the tube transfer operation.

[0054] Furthermore, the pressing assembly 31 includes a push rod 311, a pressing plate 312, a ejector pin 313, and a guide cavity 314; the lower end of the push rod 311 is provided with a pressing plate 312, and multiple sets of ejector pins 313 are provided on the pressing plate 312.

The ejector pins 313 are provided in the limiting channels, and the limiting channels can limit the ejector pins 313.

[0055] It should be noted that the ejector pin 313 is positioned directly above the sample tube, which facilitates the pushing of multiple sample tubes to disengage them from the elastic clamping assembly 2.

[0056] Preferably, the push rod 311 is manually operated, which drives the pressing plate 312 to descend. The pressing plate 312 drives multiple sets of ejector pins 313 to push multiple sets of sample tubes simultaneously, thereby completing the transfer of sample tubes.

[0057] Furthermore, a push button 315 is provided at the upper end of the push rod 311, and the push button 315 is located on the outside of the housing mechanism 1.

[0058] Ideally, manual operation is conveniently achieved by pushing button 315.

[0060] Preferably, by setting the spring-back limiting component 32, the pressing component 31 can automatically spring back to the initial position after the sample tube is pushed, which is convenient for the next sample extraction. Furthermore, by setting the spring-back limiting component 32, the situation of pressing too hard during manual pressing can be avoided.

[0061] Furthermore, the rebound limiting component 32 includes an elastic telescopic member 321, a guide cavity 314, a pressing plate 312, and a snap-fit ​​protrusion 322; the elastic telescopic member 321 is disposed between the guide cavity 314 and the pressing plate 312, and the snap-fit ​​protrusion 322 is disposed inside the elastic telescopic member 321. The upper end of the snap-fit ​​protrusion 322 is connected to the pressing plate 312, and the lower end of the snap-fit ​​protrusion 322 is a certain distance away from the upper end of the guide cavity 314.

[0062] Preferably, the elastic telescopic component 321 can be a spring, but other elastic structures can also be used.

[0063] Preferably, the guide cavity 314 is fixedly disposed inside the housing mechanism 1, and the upper end of the guide cavity 314 can drive the elastic telescopic member 321 to push the pressing plate 312 and the ejector pin 313 to rebound.

[0064] Preferably, by setting the snap-fit ​​protrusion 322, when the snap-fit ​​protrusion 322 touches the upper end of the guide cavity 314 during pressing, the push rod 311, the pressing plate 312, and the ejector pin 313 cannot descend. At this time, the sample tube is in the state of being pushed out of the elastic clamping assembly 2, which facilitates the operator's operation and feedback.

[0065] Furthermore, the housing mechanism 1 includes a guide shell 11, a sealing plate shell 12, and a guide cavity 314; the guide cavity 314 is located at the lower end of the guide shell 11, the guide shell 11 is connected to the sealing plate shell 12, and the guide shell 11 can limit the telescopic pressing mechanism 3.

[0066] Furthermore, the guide shell 11 is also provided with a push rod limiting block 13 and a push rod 311 inside. The push rod limiting block 13 can guide and limit the push rod 311.

[0067] In summary, this utility model, by setting a fixing member 21 and an elastic member 22 for clamping the sample tube 9, allows the sample tube 9 to be easily clamped by the fixing member 21 and the elastic member 22, thereby improving the efficiency of extracting the sample tube 9. By setting multiple sets of ejector pins 313 on the pressing plate 312, and limiting the multiple sets of ejector pins 313 through multiple sets of limiting channels on the guide cavity 314, multiple sets of sample tubes can be ejected simultaneously through the multiple sets of ejector pins 313, thus improving the efficiency of batch placement of sample tubes 9.
