Description

Technical Field

[0001] This utility model relates to an auxiliary device for EP tubes, specifically an auxiliary device for positioning EP tubes. Background Technology

[0002] In current testing processes, automated testing systems typically employ specific tracks, grippers, or conveyor devices for precisely grasping, moving, and positioning sample containers. EP tubes consist of a cap and a body, with a raised ring at the top of the body and a connector on the ring to connect to the cap. The bottom of the body is tapered. Because EP tubes cannot stand upright without external force and cannot be properly aligned with tracks, grippers, or conveyor devices, they cannot be effectively grasped or positioned, making them incompatible with automated testing systems. Sample transfer is required during testing; specifically, the sample is manually transferred from the EP tube to a test tube. During transfer, the sample is highly susceptible to contamination. Improper operation, an unclean environment, or problems with the tools themselves can all become sources of contamination, affecting sample purity and the accuracy of test results. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary device for EP tube positioning. The technical problem to be solved is how to adapt the EP tube to the automated testing system of the production line, eliminate sample transfer operations, and solve the problem of contamination caused by sample transfer.

[0004] This utility model is achieved through the following technical solution:

[0005] An auxiliary device for positioning EP tubes is provided, which is used to place in the placement hole of a sample tube holder, with one auxiliary device corresponding to one placement hole; it includes a support part and an extension part, the extension part being connected to the bottom of the support part; the extension part is used to extend into the placement hole of the sample tube holder.

[0006] The aforementioned support portion is provided with a first through hole, which is used to fit the EP tube body; the upper surface of the aforementioned support portion is used to abut against the lower surface of the EP tube protrusion ring, and the lower surface of the support portion is used to abut against the upper surface of the sample tube holder.

[0007] The EP tubes are secured by the aforementioned support section, and the auxiliary device is fixed to the sample tube holder by the extension section, making the EP tubes compatible with the automated testing system. Specifically, the extension section extends into the placement hole of the sample tube holder, ensuring that each EP tube can be positioned in the predetermined position; the first through hole on the support section is used to fit the EP tube body and fix the EP tube to the auxiliary device. During the testing process, the EP tubes are positioned by clamping and fixing the auxiliary device, making the EP tubes compatible with the automated testing system. This eliminates the need for sample transfer before and after testing, not only solving the problem of contamination caused by sample transfer but also reducing manual operation and improving efficiency.

[0008] Furthermore, the aforementioned support portion includes a support sleeve and a support plate, wherein the support plate is disposed on the lower surface of the support sleeve;

[0009] The support plate extending from the aforementioned support sleeve is provided with a groove, which is used to limit the EP pipe cap.

[0010] The aforementioned support sleeve is used to mount the EP tube body, while the support plate provides bottom support, which not only increases the vertical stability of the EP tube but also helps prevent the EP tube from swaying or shifting in the horizontal direction. By setting grooves on the support plate, the EP tube cap is limited, preventing the EP tube cap from obstructing the sample during automated processing and ensuring the smooth progress of the testing process.

[0011] Furthermore, the aforementioned support plate is provided with a first side and a second side that are parallel to each other.

[0012] The first and second sides are opposite each other. When the auxiliary device is placed on the sample tube holder manually, the first and second sides are on the same plane as the two sides of the sample tube holder, which makes it easier for the manual to place the sample correctly.

[0013] Furthermore, the outer sleeve of the aforementioned support portion is provided with a force-bearing portion, which is used to contact the gripper.

[0014] The aforementioned force-bearing part serves as the force-bearing point, facilitating the gripper's grasping of the auxiliary device.

[0015] Furthermore, a guide groove is provided on the side of the aforementioned force-bearing part, which corresponds to the groove.

[0016] The correspondence between the guide groove and the groove on the support plate ensures that when the EP tube is fixed in the auxiliary device, the EP tube cap extends through the guide groove into the groove, thus fixing the cap.

[0017] Furthermore, the aforementioned force-bearing portion extends beyond the upper surface of the support portion, and the force-bearing portion extending beyond the upper surface of the support portion extends toward the axis of the support portion.

[0018] The force-bearing part extending from the upper surface of the aforementioned support can contact the convex ring of the EP tube, which can limit the range of motion of the EP tube and thus prevent the tube cap from detaching from the groove due to the EP tube exceeding its range of motion.

[0019] Furthermore, the aforementioned extension is provided with a second through hole, which is used to accommodate the EP tube body.

[0020] The space for accommodating the EP tube body is increased to prevent the EP tube body from being too long and thus the first through hole cannot be fully accommodated, and the lower surface of the convex ring cannot contact the upper surface of the support part, thus forming a fixed structure.

[0021] Furthermore, the aforementioned support and extension are connected by threads.

[0022] Detachable connection is achieved through threads.

[0023] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0024] The EP tubes are secured by the aforementioned support section, and the auxiliary device is fixed to the sample tube holder by the extension section, making the EP tubes compatible with the automated testing system. Specifically, the extension section extends into the placement hole of the sample tube holder, ensuring that each EP tube can be positioned in the predetermined position; the first through hole on the support section is used to fit the EP tube body and fix the EP tube to the auxiliary device. During the testing process, the EP tubes are positioned by clamping and fixing the auxiliary device, making the EP tubes compatible with the automated testing system. This eliminates the need for sample transfer before and after testing, not only solving the problem of contamination caused by sample transfer but also reducing manual operation and improving efficiency.

The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0032] First embodiment:

[0033] An auxiliary device for positioning EP tubes is provided, wherein the auxiliary device is placed in a placement hole of a sample tube holder, with one auxiliary device corresponding to one placement hole; combined with Figure 1 The auxiliary device includes a support part 1 and an extension part 2. The extension part 2 is connected to the bottom of the support part 1. The support part 1 is provided with an internal thread, and the extension part 2 is provided with an external thread. The support part 1 and the extension part 2 are connected by threads to achieve detachability. The extension part 2 is used to extend into the placement hole of the sample tube holder.

[0034] The aforementioned support part 1 is provided with a first through hole 13, which is used to fit the EP tube body 41; the upper surface of the aforementioned support part 1 is used to abut against the lower surface of the EP tube protrusion ring 42, and the lower surface of the support part 1 is used to abut against the upper surface of the sample tube holder.

[0035] The EP tube is fixed by the support part 1, and the auxiliary device is fixed to the sample tube holder by the extension part 2, so that the EP tube can be adapted to the automated testing system. Specifically, the extension part 2 extends into the placement hole of the sample tube holder to ensure that each EP tube can be positioned in the predetermined position; the first through hole 13 on the support part 1 is used to fit the EP tube body 41 and fix the EP tube to the auxiliary device. During the testing process, the EP tube is positioned by clamping and fixing the auxiliary device, so that the EP tube can be adapted to the automated testing system. This eliminates the need for sample transfer before and after testing, which not only solves the problem of contamination caused by sample transfer, but also reduces manual operation and improves efficiency.

[0036] Since there is no need to transfer samples, the entire testing process is simplified, reducing both operation time and complexity. Sample transfer involves contact with various surfaces, increasing the risk of contamination. This auxiliary device avoids unnecessary sample transfer and contact by fixing the EP tube to the sample tube holder, thus reducing the possibility of contamination. Contaminated samples may lead to inaccurate or misleading test results. By reducing the risk of contamination, this auxiliary device helps ensure the accuracy and reliability of test results.

[0037] Second embodiment:

[0038] Based on the first embodiment, combined with Figure 1 and Figure 2 The aforementioned support part 1 includes a support sleeve 11 and a support plate 12, wherein the support plate 12 is disposed on the lower surface of the support sleeve 11;

[0039] The support plate 12 extending from the support sleeve 11 is provided with a groove 14, which is used to limit the EP tube cap 43.

[0040] The aforementioned support sleeve 11 is used to cover the EP tube body 41, while the support plate 12 provides bottom support, which not only increases the stability of the EP tube in the vertical direction, but also helps to prevent the EP tube from shaking or shifting in the horizontal direction. By providing a groove 14 on the support plate 12, the tube cap 43 of the EP tube is limited, preventing the tube cap 43 from obstructing the sample during automated processing, thus ensuring the smooth progress of the testing process.

[0041] When processing EP tubes, the automated testing system typically needs to open the tube cap 43 to access the sample. The tube cap 43 is fixed in a predetermined position by the groove 14, thus keeping the tube cap 43 in the open state.

[0042] Third embodiment:

[0043] Based on the second embodiment, combined with Figure 1 The aforementioned support plate 12 is provided with a first side 15 and a second side 16 that are parallel to each other.

[0044] The first side 15 and the second side 16 are opposite each other. When the auxiliary device is placed on the sample tube holder by the operator, the first side 15 and the second side 16 are on the same plane as the two sides of the sample tube holder, which makes it easy for the operator to place the sample correctly.

[0045] Fourth embodiment:

[0046] Based on the second embodiment, combined with Figure 1 and Figure 2 The support sleeve 11 is provided with a force-receiving part 3, which is used to contact the gripper.

[0047] The aforementioned force-bearing part 3 serves as a force-bearing point, facilitating the gripper's gripping of the auxiliary device.

[0048] In a specific embodiment, a guide groove 31 is provided on the side of the force-bearing part 3, which corresponds to the groove 14.

[0049] The correspondence between the guide groove 31 and the groove 14 on the support plate 12 ensures that when the EP tube is fixed in the auxiliary device, the EP tube cap 43 extends through the guide groove 31 into the groove 14, thereby fixing the cap 43.

[0050] In a specific embodiment, the force-bearing part 3 extends out of the upper surface of the support part 1, and the force-bearing part 3 extending out of the upper surface of the support part 1 extends toward the axis of the support part 1.

[0051] The force-bearing part 3 extending from the upper surface of the support part 1 can contact the protruding ring 42 of the EP tube, which can limit the range of motion of the EP tube and thus prevent the tube cap 43 from falling out of the groove 14 due to the EP tube exceeding the range of motion.

[0052] Fifth embodiment:

[0053] Based on any of the above embodiments, combined with Figure 3 The aforementioned extension 2 is provided with a second through hole 21, which is used to accommodate the EP tube body 41.

[0054] The space for accommodating the EP tube body 41 is expanded to prevent the EP tube body 41 from being too long, which would prevent the first through hole 13 from being fully accommodated and the lower surface of the convex ring 42 from contacting the upper surface of the support part 1, thus forming a fixed structure.

[0055] The auxiliary device is used as follows:

[0056] First, the support part 1 and the extension part 2 are connected together by threads to assemble the auxiliary device into a whole;

[0057] Secondly, the EP tube is placed on the auxiliary device manually;
