Description

Technical Field

[0001] The present invention relates to the technical field of analytical instruments, in particular to a sample loading mechanism and an analyzer. Background Art

[0002] In modern medical clinical testing laboratories, analyzers typically utilize automatic sample introduction modules with a dual-claw structure to push the sample introduction component placed by the user into the loading area to a designated location. Existing dual-claw automatic sample introduction modules feature dual claws mounted on a fixed bracket. The vertical position of the bracket relative to the loading platform is primarily determined by the bracket's height and the dimensions of the platform's supporting components. Therefore, the distance between the dual claws and the loading platform panel cannot be adjusted. Because dual-claw structures are typically constructed from sheet metal, which is prone to deformation, this can lead to inconsistent heights between the dual claws and the loading platform panel. If the distance between the double claws and the loading platform panel is too small, it is very easy for the double claw mechanism to collide and interfere with the loading platform panel; and if the distance between the two is too large, during the bidirectional loading process, the double claw mechanism will cause the height of the sample injection component to be inconsistent when it drives the sample injection component to retreat, and the sample injection component will be brought down, causing the equipment to malfunction and fail to load the sample injection component smoothly. In particular, when the user places a new sample injection component behind the double claw structure, the double claws need to bypass the sample injection component. If the distance between the double claws and the loading platform panel is inconsistent, the position at which they abut on the sample injection component will also be different. In this way, when the double claws load the new sample injection component, it is easy to lead the sample injection component crooked, and then it will get stuck, causing the machine to malfunction.

[0030] Example 1:

[0031] like Figure 4 As shown in the three-dimensional diagram of the sample loading mechanism, this embodiment 1 provides a sample loading mechanism 10, which can adaptively adjust the height between the feeding component and the loading table panel, so as to avoid interference between the feeding component and the loading table panel, and solve the problem of the feeding component bringing the sample components upside down or crooked during bidirectional loading, thereby causing machine failure.

[0032] Please refer to Figure 1 The sample loading mechanism provided in this embodiment includes a driving mechanism 100, a loading platform panel 200, a carrier 300, a feeding assembly 400, and a supporting assembly 500. The loading platform panel is provided on the support body of the sample loading mechanism and is used to carry the sample injection component 1800 so that the sample injection component 1800 can be moved along the injection direction to the injection position located at one end of the loading platform panel 200. It can be understood that the loading platform panel 200 can be selected as a rectangular plate. The sample injection component is first placed at one end of the rectangular plate (i.e., the loading position) by a manual or automatic pushing device, and then pushed to the other end of the rectangular plate (i.e., the injection position) by the feeding assembly 400 along the injection direction.

[0033] In addition, the carrier 300 is located below the loading platform panel 200 and has a first branch 310 and a second branch 320 extending to both sides of the loading platform panel 200. The first branch 310 and the second branch 320 provide pre-pressure toward the loading platform panel 200. The carrier 300 is coupled to the driving mechanism 100 and moves back and forth along the injection direction under the drive of the driving mechanism 100; the feeding assembly 400 includes a first finger 410 on the first branch 310 of the carrier 300 and a second finger 420 on the second branch 320, respectively, and the first finger 410 and the second finger 420 are respectively provided on the loading platform panel 20 0 extends to the top of the loading platform panel 200 on both sides to push the sample injection component to move; the abutment assembly 500 includes a first abutment 510 and a second abutment 520, the first abutment 510 is located on the first branch 310 and is arranged toward the loading platform panel 200, and the second abutment 520 is located on the second branch and is arranged toward the loading platform panel 200; and the first abutment 510 is arranged close to the first pusher claw 410, and the second abutment 520 is arranged close to the second pusher claw 420, and the pre-pressure makes the first abutment 510 and the second abutment 520 always abut against the loading platform panel 200.

[0034] To avoid the problem of the sample feed component 1800 being tilted or distorted due to the inconsistent position of the feed assembly 400 abutting the sample feed component 1800 during the sample feed component loading process, that is, the height difference between the feed assembly 400 and the loading platform panel 200, the inventors carefully studied existing sample feed loading mechanisms and found that the feed assembly is generally mounted on a fixed rigid support. Due to its own installation error, the position of the feed assembly abutting the sample feed component is different. For the commonly used two-way loading sample feed loading mechanism, this installation error does not have a significant impact on the sample feed component during the sample feeding. However, when the feed assembly is retracted, especially when the user places a new sample feed component behind the feed assembly, the feed assembly needs to go around the new sample feed component. At this time, due to the inconsistent height of the two sides of the feed component, the feed component may be tilted or distorted, thereby causing the machine to malfunction. The root cause of this phenomenon is that the feed assembly is at different heights from the loading platform panel and does not automatically adjust its height from the loading platform panel.

[0035] For this, please refer to Figure 1Through repeated analysis and improvement, the inventors have identified a preferred method: replacing the support member 300 for mounting the feeding assembly 400 with an elastic support body. The middle portion of the elastic support body is mounted on the first mounting block 600 at a distance less than the height of the first abutting member 510 and the second abutting member 520. This generates a preload toward the loading platform panel 200. The first mounting block 600 serves as a mounting support, ensuring the elastic support body is securely mounted and ensuring that the elastic support body follows the first mounting block 600 in axial movement along the injection direction under the drive mechanism 100. Specifically, the elastic support body provides a spring force toward the loading platform panel 200, ensuring that the first abutting member 510 and the second abutting member 520 always press against the bottom of the loading platform panel 200 during operation of the feeding assembly, thereby ensuring that the first and second pusher claws 410 and 420 are at the same height from the loading platform panel 200. In this embodiment, the first and second branches 310 and 320 of the elastic support body are integrally formed.

[0036] Furthermore, since the middle portion of the elastic support body is installed on the first mounting block 600 at a height less than that of the first abutting member 510 and the second abutting member 520, a preload force is generated toward the loading platform panel 200. This preload force is concentrated in the middle portion of the elastic support body. In order to reduce the height difference between the first and second pusher claws 410 and 420 and the loading platform panel 200, the first abutting member 510 and the second abutting member 520 are symmetrically arranged relative to the loading platform panel 200, so that the preload force provided by the elastic support body can be evenly distributed; and they are respectively close to the first and second pusher claws 410 and 420, so that the preload force provided by the elastic support body can affect the height of the first and second pusher claws 410 and 420 from the loading platform panel 200 to the greatest extent, thereby eliminating the height difference between the pusher claws on both sides and the loading platform panel 200.

[0037] In one embodiment, the first abutting member 510 and the second abutting member 520 are sliders fixed to an elastic support body. Specifically, the sliders can be cylindrical, cubic, etc., and are fastened to the elastic support body by screws, bolts, etc., which ensures a secure installation and is easy to install and replace.

[0038] Furthermore, at least the portion of the slider that contacts the loading platform panel 200 is made of wear-resistant material. This makes the slider have excellent wear resistance, reduces friction loss during the reciprocating movement of the sample injection, increases the slider's service life, and reduces replacement costs.

[0039] In one embodiment, the first abutting member 510 and the second abutting member 520 are formed by the first and second protrusions of the elastic support body facing the loading platform panel 200. Therefore, the first and second protrusions have a higher connection strength with the elastic support body, and the number of parts is reduced, making the overall device more compact.

[0040] Furthermore, a wear-resistant coating is formed on the portions of the first and second protrusions that abut the loading platform panel 200. This effectively reduces friction and wear between the first and second protrusions and the loading platform panel 200, thereby increasing the designed service life. Specifically, the wear-resistant coating can be a ceramic wear-resistant layer, a metal wear-resistant layer, a resin wear-resistant layer, or the like.

[0041] Please refer to Figure 2 In a more preferred embodiment, the elastic support body is rotatably mounted on the first mounting block 600 via the first rotating shaft 700. The elastic support body can rotate via the first rotating shaft 700, thereby enhancing the adaptability of the first and second shift claws 410 and 420 in the height direction from the loading platform panel 200.

[0042] Please continue to refer to Figure 1 and 2 The shifting assembly 400 includes a first elastic return member 1300, a second elastic return member 1400, a first shifter dog mounting shaft 1500, and a second shifter dog mounting shaft 1600. The first shifter dog 410 is rotatably mounted on the first branch 310 via the first shifter dog mounting shaft 1500, wherein one end of the first elastic return member 1300 is connected to the first branch 310 and the other end is connected to the first shifter dog 410. The second shifter dog 420 is rotatably mounted on the second branch 320 via the second shifter dog mounting shaft 1600, wherein one end of the second elastic return member 1400 is connected to the second branch 320 and the other end is connected to the second shifter dog 420. Therefore, by achieving rotatability relative to the first and second pusher claw mounting shafts 1500 and 1600, the first and second pusher claws 410 and 420 can rotatably contact the sample injection component 1800, thereby realizing the sample injection and retraction functions. In particular, when the user places a new sample injection component 1800 behind the feeding assembly 400, the feeding assembly 400 needs to bypass the sample injection component 1800 and push it in the injection direction to the sample injection position. In addition, the first and second elastic return members 1300 and 1400 can optionally be springs. The rebound tension can reset the first and second pusher claws 410 and 420 after the sample injection is completed, facilitating the next sample injection operation and improving the performance of the device.

[0043] Furthermore, the sample loading mechanism 10 further includes a guide member 1700, on which the first mounting block 600 is slidably mounted. Thus, through the guiding effect of the guide member 1700, it is possible to ensure that the first mounting block 600 can reciprocate along a preset path axis under the drive of the drive mechanism 100, thereby improving the stability and reliability of the sample loading operation. The guide member can be a slide rail or a guide rod with a smooth outer wall. Please continue to refer to Figure 1 and 2The drive mechanism 100 is fixed to the sample loading mechanism support body and can be a drive motor that drives the first mounting block 600 along the guide member 1700 via a belt drive, or a cylinder that directly drives the first mounting block 600 to reciprocate. In one embodiment, the drive motor includes a driving member, a driving pulley connected to the driving member, a driven pulley spaced apart from the driving pulley, a belt fitted over the driving and driven pulleys, and a transmission connector fixed to the belt. The transmission connector is connected to the first mounting block 600, which is slidably mounted on the guide member 1700. This connection structure is simple, the transmission is reliable, and the manufacturing and use costs are low.

[0044] The sample loading mechanism provided in this embodiment has a supporting member which is an elastic supporting body, which is located below the loading table, and the middle portion of which is installed on the first mounting block at a distance less than the height of the first abutting member and the second abutting member, thereby generating a pre-pressure toward the loading table panel. The first abutting member and the second abutting member are provided near the first and second claws, so that the concentrated pre-pressure generated in the middle portion of the elastic supporting member is symmetrically dispersed on the first and second claws, so that the pre-pressure provided by the elastic supporting body can maximize the influence on the distance between the first and second claws and the loading table panel, thereby eliminating the height difference between the left and right first and second claws and the loading table panel, and when When the first and second shift claws are at different heights from the loading table panel, the pre-pressure provided by the elastic support body toward the loading table panel will change on the first and second branches of the elastic support body, thereby affecting the force acting on the loading table panel by the first abutment member and the second abutment member, thereby adjusting the distance between the first shift claw near the first abutment member and the second shift claw near the second abutment member extending above the loading table panel, so that the first shift claw and the second shift claw can automatically adapt to the height of the loading table panel during the operation of the sample injection component, so that the two are always kept at a fixed height, that is, the position of the abutment against the sample injection component is the same, thereby preventing the sample injection component from being knocked over during bidirectional loading of the sample injection loading mechanism, thereby improving reliability.

[0045] Example 2:

[0046] The second embodiment provides a sample injection and loading mechanism.

[0047] like Figure 3 As shown, the loading platform panel 200 includes a drive mechanism 100, a loading platform panel 200, a carrier 300, a feeding assembly 400, and a supporting assembly 500. The loading platform panel is used to carry the sample injection component 1800 so that the sample injection component 1800 can be moved along the injection direction to the injection position located at one end of the loading platform panel 200. It can be understood that the loading platform panel 200 can be a rectangular plate. The sample injection component is first placed at one end of the rectangular plate (i.e., the loading position) by manual or automatic pushing equipment, and then automatically pushed to the other end of the rectangular plate (i.e., the injection position) by the feeding assembly in the injection direction.

[0048] In addition, the carrier 300 is located below the loading platform panel 200 and has a first branch 310 and a second branch 320 extending to both sides of the loading platform panel 200. The first branch 310 and the second branch 320 provide pre-pressure toward the loading platform panel 200. The carrier 300 is coupled to the driving mechanism 100 and moves back and forth along the injection direction under the drive of the driving mechanism 100; the feeding assembly 400 includes a first finger 410 on the first branch 310 of the carrier 300 and a second finger 420 on the second branch 320, respectively, and the first finger 410 and the second finger 420 are respectively provided on the loading platform panel 200. The two sides extend above the loading platform panel 200 to push the sample injection component to move; the supporting assembly 500 includes a first supporting member 510 and a second supporting member 520, the first supporting member 510 is located on the first branch 310 and is arranged toward the loading platform panel 200, and the second supporting member 520 is located on the second branch and is arranged toward the loading platform panel 200; and the first supporting member 510 is arranged close to the first pusher claw 410, and the second supporting member 520 is arranged close to the second pusher claw 420, and the pre-pressure makes the first supporting member 510 and the second supporting member 520 always abut against the loading platform panel 200.

[0049] In this embodiment, the first branch 311 and the second branch 321 of the carrier 300, which mounts the transfer assembly 400, are made of a rigid material. The first branch 311 and the second branch 321 are symmetrically arranged below the loading platform panel 200, forming two separate components rather than a single piece, making them easy to disassemble and replace.

[0050] Please continue to refer to Figure 3 In one embodiment, the sample loading mechanism 10 includes a second mounting block 800, the first branch 311 being rotatably mounted on the second mounting block 800 via a second rotating shaft 900, and the second branch 321 being rotatably mounted on the second mounting block 800 via a third rotating shaft 1000. Thus, the rotatability provided by the second rotating shaft 900 and the third rotating shaft 1000 provides the first branch 311 and the second branch 321 with a certain degree of adaptive adjustability.

[0051] Based on the above embodiment, the sample loading mechanism 10 also includes a first spring 1100 and a second spring 1200; one end of the first spring 1100 is connected to the first branch 311, and the other end is connected to the second mounting block 800; one end of the second spring 1200 is connected to the second branch 321, and the other end is connected to the second mounting block 800. During the operation of the sample loading mechanism, the first branch 311 and the second branch 321 are connected to the second rotating shaft 900 and the third rotating shaft 1000 respectively through the tension of the first spring 1100 and the second spring 1200, providing a pre-pressure toward the loading platform panel 200. The pre-pressure makes the first abutting member 510 and the second abutting member 520 always press against the loading platform panel 200; and the first abutting member 510 is arranged close to the first pusher claw 410, so that the pre-pressure generated by the first spring 1100 can maximize the influence of the height of the first pusher claw 410 from the loading platform panel 200 through the first abutting member 510, and the second abutting member 520 is arranged close to the second pusher claw 420, so that the pre-pressure generated by the second spring 1200 can maximize the influence of the height of the second pusher claw 420 from the loading platform panel 200 through the second abutting member 520.

[0052] Please continue to refer to Figure 3 The first spring 1100 and the second spring 1200 can be a torsion spring, a tension spring, etc. During the bidirectional loading process of the sample loading mechanism 10, when the height of the first pusher claw 410 and the second pusher claw 420 are inconsistent with the height of the loading table panel 200, the first spring 1100 and the second spring 1200 themselves deform to generate a rebound tension. The rebound tension can ensure that the first branch 311 and the second branch 321 can be rotated and reset after the rigid deformation. At this time, the first abutting member 510 and the second abutting member 520 that are always tightly pressed against the loading table panel 200 are adjusted due to the rebound tension. By adjusting the pre-pressure near the first pusher claw 410 and the second pusher claw 420, the distance between the first pusher claw 410 near the first abutting member 510 and the second pusher claw 420 extending above the loading platform panel is changed, that is, the height of the first pusher claw 410 and the second pusher claw 420 from the loading platform panel 200 is adjusted, so that the sample loading mechanism 10 can automatically adapt to the height of the loading platform panel during loading, so that the two are always maintained at a fixed height, thereby avoiding interference with the loading platform panel 200 and the sample loading component 1800 being distorted during retraction.

[0053] Furthermore, the sample loading mechanism 10 also includes a guide member 1700, on which the second mounting block 800 is slidably mounted. The guiding action of the guide member 1700 ensures that the second mounting block 800 reciprocates along a predetermined path axis under the drive of the drive mechanism 100, thereby improving the smoothness and reliability of the sample loading operation. The guide member can be a slide rail or a guide rod with a smooth outer wall. The drive mechanism 100 is fixed to the sample loading mechanism support body and can be a drive motor that drives the second mounting block 800 along the guide member 1700 via a belt drive, or a cylinder that directly drives the second mounting block 800 to reciprocate. In one embodiment, the drive motor includes a drive member, a driving pulley connected to the drive member, a driven pulley spaced apart from the driving pulley, a belt mounted on the driving and driven pulleys, and a transmission connector fixed to the belt. The transmission connector is connected to the second mounting block 800, which is slidably mounted on the guide member 1700. The connection structure is simple, the transmission is reliable, and the manufacturing and use costs are low.

[0054] The carrier of the sample injection and loading mechanism of this embodiment is a first branch and a second branch that are symmetrically arranged separately, and the first branch and the second branch are made of rigid material, and a pre-pressure toward the loading platform panel is formed by the second rotating shaft, the third rotating shaft, the first spring, and the second spring, so that during the bidirectional loading process of the loading mechanism, the first pusher claw and the second pusher claw are at the same height from the loading platform panel, avoiding interference and collision, and machine failure caused by the sample injection component being distorted and then stuck, thereby improving the reliability of the equipment, and when it is necessary to replace the feeding component or the supporting component, only one side needs to be disassembled for replacement, and there is no need to replace the sample injection and loading mechanism carrier as a whole, which is convenient for user operation and makes the replacement of the carrier more efficient.
