Description

Technical Field

[0001] This utility model relates to the field of test tube grasping equipment technology, and in particular to a test tube clamping and transferring device. Background Technology

[0002] After using test tubes, places such as hospital blood transfusion departments, blood banks, and laboratories need to collect test tubes, such as multiple test tubes containing collected samples.

[0003] The existing test tube recycling process basically involves staff manually placing the test tubes onto fixed supports. For placement positions that are far away on the fixed supports, staff need to stretch their arms or get up from their seats to place them. This process is generally inefficient and can easily cause arm pain for staff over a long period of time.

[0004] Traditional gripping devices are generally designed for gripping fixed supports. They can achieve precise identification and gripping when combined with a vision recognition module. However, their vertical and telescopic gripping methods are not flexible enough in use. The components have a large range of movement, especially the telescopic range, which leads to relatively greater wear on the telescopic components. Furthermore, the guide rails and motors need to be calibrated after moving the support.

[0005] Therefore, there is an urgent need for a test tube clamping and transfer device that can clamp, transfer, and position test tubes to reduce the burden on staff. Utility Model Content

[0007] The clamping assembly has two opposing clamping arms rotatably mounted on its free end. Each clamping arm has a toothed surface at one end near its pivot, and the teeth of the two clamping arms mesh. Each clamping arm has a groove, and a first pin is installed in the groove of the first clamping arm, with one end of the first pin extending out of the surface of the first clamping arm. A second pin is installed in the groove of the second clamping arm. The two ends of a tension spring are connected to the first pin and the second pin, respectively. The sides of each clamping arm have shaped grooves, and the two shaped grooves cooperate to clamp the test tube. The tension spring ensures that the two clamping arms clamp the test tube securely.

[0008] The first clamping arm has a drive gear mounted on its shaft. The drive gear meshes with the drive gear of the clamping drive motor of the clamping assembly. The drive gear has two limiting flanges. The protruding end of the first pin is located between the two limiting flanges.

[0010] In some embodiments, the translation component includes: a first guide rail component and a second guide rail component. The upper and lower ends of the longitudinal movement component are respectively connected to the first and second guide rail components. The first guide rail component is equipped with a first belt drive component. A first drive motor drives the first belt drive component, and the first belt drive component drives the longitudinal movement component to perform translation.

[0011] In some embodiments, the longitudinal movement component is provided with a second belt drive component and a longitudinal guide rail. The longitudinal guide rail is connected to a support, and the support is connected to the rotating arm. A second drive motor drives the second belt drive component, and the second belt drive component drives the support to perform longitudinal movement.

[0012] Furthermore, the support is connected to the first side of the conveyor belt of the second belt drive assembly, and the second side of the drive belt of the second belt drive assembly is connected to a counterweight, which performs longitudinal movement via a guide rail.

[0013] In some embodiments, the rotating arm is equipped with a drive shaft and a third drive motor. The third drive motor drives the drive shaft to rotate via a driven gear. The drive shaft is connected to the clamping assembly and drives the clamping assembly to rotate.

Detailed Implementation

[0020] To make the above-mentioned objectives, features, and advantages of this utility model more readily understood, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] This utility model discloses a test tube clamping and transferring device, such as... Figure 1 , Figure 2 As shown, it includes: a translation component 1, a longitudinal movement component 2, a rotating arm 3, and a clamping component 4. The translation component 1 drives the longitudinal movement component 2 to perform translation, the longitudinal movement component 2 drives the rotating arm 3 to perform longitudinal movement, the rotating arm 3 drives the clamping component 4 to rotate, and the clamping component 4 is used to clamp the test tube 5.

[0022] Combination Figure 3 , Figure 4As shown, the free end of the clamping assembly 4 is rotatably mounted with two opposing clamping arms 40. Each clamping arm 40 has a toothed surface 401 at one end near its pivot 400. The toothed surfaces 401 of the two clamping arms 40 mesh. Each clamping arm 40 has a groove 402. A first pin 42 is installed in the groove 402 of the first clamping arm 40, and one end of the first pin 42 extends out of the surface of the first clamping arm 40. A second pin 43 is installed in the groove 402 of the second clamping arm 40. The two ends of a tension spring 44 are connected to the first pin 42 and the second pin 43, respectively. A groove 45 is provided on the side of each clamping arm 40. The two grooves 45 cooperate to clamp the test tube 5. The tension spring 44 ensures that the two clamping arms 40 clamp the test tube 5 securely.

[0023] The first clamping arm 40 has a rotating shaft 400 equipped with a transmission gear 41, which meshes with the drive gear 46 of the clamping drive motor 47 of the clamping assembly 4. The transmission gear 41 is provided with two limiting flanges 410, and the protruding end of the first pin 42 is located between the two limiting flanges 410.

[0024] When the first pin 42 engages with the limiting flange 410, the transmission gear 41 drives the clamping arm 40 to rotate.

[0025] It should be noted that the design of the tension spring 44 ensures that the tension applied when pulling the two clamping arms 40 will not cause the test tube 5 to be damaged. Furthermore, when in the untensioned state, it limits the closing of the two clamping arms 40. At this time, the distance between the two clamping arms 40 also meets the condition that the test tube 5 will not be damaged, thus preventing damage to the test tube 5 under the drive of the clamping drive motor 47. The test tube clamping and transferring device is equipped with an external or internal main control and power module. The clamping drive motor 47 can be equipped with a force feedback module to determine whether the test tube is currently clamped in place.

[0026] Specifically, in combination Figure 1 As shown, the translation component 1 includes: a first guide rail component 10 and a second guide rail component 11. The upper and lower ends of the longitudinal movement component 2 are respectively connected to the first and second guide rail components. The first guide rail component 10 is equipped with a first belt drive component 100. The first drive motor 12 drives the first belt drive component 100. The first belt drive component 100 drives the longitudinal movement component 2 to perform translation.

[0027] The longitudinal moving component 2 is provided with a second belt drive component 20 and a longitudinal guide rail 21. The longitudinal guide rail 21 is connected to the support 200, and the support 200 is connected to the rotating arm 3. The second drive motor 22 drives the second belt drive component 20, and the second belt drive component 20 drives the support 200 to perform longitudinal movement.

[0028] The support 200 is connected to the first side of the conveyor belt of the second belt drive assembly 20, and the second side of the drive belt of the second belt drive assembly 20 is connected to the counterweight 201, which moves longitudinally via a guide rail.

[0029] Specifically, in combination Figure 2 , Figure 3 As shown, the rotating arm 3 is equipped with a drive shaft 30 and a third drive motor 31. The third drive motor 31 drives the drive shaft 30 to rotate through a driven gear 300. The drive shaft 30 is connected to the clamping assembly 4. The drive shaft 30 drives the clamping assembly 4 to rotate, and the rotation angle range is 0-180 degrees.

[0030] In summary, the device achieves the clamping of test tubes using a clamping assembly, and maintains this clamping position via a tension spring even when the device is powered off, preventing the test tubes from falling. The clamping assembly achieves vertical, horizontal, and rotational movement through a translation component, a longitudinal movement component, and a rotating arm, thus achieving greater flexibility for clamping test tubes in different positions. It eliminates the need for traditional fixed-frame guide rail movement, utilizing the rotating arm for fine-tuning and alignment, reducing the need for frequent calibration of the translation and longitudinal movement components. The rotation of the arm also reduces the movement step in some positions, improving efficiency. Furthermore, the device, in conjunction with an existing vision recognition module, enables a more efficient automated test tube clamping process, reducing the workload of operators.

[0031] The embodiments described above are merely illustrative of one or more implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
