Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a separable, linked reciprocating motion mechanism system. Background Technology

[0002] Medical testing instruments, as commonly used testing equipment in medical facilities, are widely used in various laboratories and medical institutions. On the one hand, due to the continuous improvement in the testing efficiency and increasingly powerful automatic testing capabilities of modern testing equipment, sample data can be quickly displayed for medical personnel to observe in a timely manner. However, when abnormal data samples are displayed, the sample holding device is often still moving forward in a single direction, and the puncture sampling is already aligned with the position of the next test tube sample. It is not possible to re-examine the previous abnormal sample. Most instruments require all sample testing to be completed or to be paused, and medical personnel must manually remove the abnormal sample, replace it, and click to start the test. This greatly reduces efficiency and is not automated or user-friendly. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a separable, linked reciprocating motion mechanism system that can perform continuous sample injection and instantaneous reciprocating motion, thereby meeting the requirements of retesting, in view of the above-mentioned defects of the prior art.

[0004] To achieve the above objectives, the present invention provides a separable, linked reciprocating motion mechanism system, including a first slider lever module, a second slider lever module, and an electromagnet guide module;

[0005] The first slider lever module includes a horizontal lever, a guide rail slider, and a guide rail. The guide rail is fixedly installed on the machine body, the guide rail slider is slidably connected to the guide rail, the first slider is fixedly connected to the guide rail slider, the horizontal lever is fixedly connected to the guide rail slider, and the horizontal lever is located at the top of the guide rail slider.

[0006] The second slider lever module includes a return lever, a second slider, a flange bearing, a rotary bracket, a first magnet, and a tension spring. The second slider is slidably connected to the guide rail. The return lever is fixedly connected to the second slider and is located at the top of the second slider. The inner side of the flange bearing is fixedly connected to the second slider, and the outer side of the flange bearing is fixedly connected to the rotary bracket. The first magnet is fixedly connected to the second slider. One end of the tension spring is fixedly connected to the first magnet, and the other end of the tension spring is fixedly connected to the rotary bracket.

[0007] The electromagnet guiding module includes a second magnet, a guide rod, an electromagnet mounting block, and an electromagnet. The first magnet is attached to the second magnet, the second magnet is located at the bottom of the first magnet, the electromagnet is fixedly mounted on the electromagnet mounting block, and the guide rod is fixedly connected to the electromagnet.

[0008] The first slider lever module further includes a first slider and a timing belt. The first slider is fixedly connected to the guide rail slider, and the timing belt is drivenly connected to the first slider.

[0009] The first slider lever module further includes a timing belt pressure plate, which is fixedly connected to the first slider, and the timing belt is located between the timing belt pressure plate and the first slider.

[0010] The separable, linked reciprocating motion mechanism system further includes a drive unit module, which includes a motor and a synchronous pulley. The motor is fixedly mounted on the machine body, the synchronous pulley is fixedly connected to the output end of the motor, and the synchronous belt is drivenly connected to the synchronous pulley.

[0011] The second slider is provided with a cylindrical boss, which is integrally formed with the second slider. The cylindrical boss is engaged inside the flange bearing. The rotating seat has a stepped hole, and the flange bearing is engaged inside the stepped hole.

[0014] The beneficial effects of this invention are reflected in the following: It achieves two functions—continuous sample feeding and test tube rack retraction—through the separation and linkage of the first and second slider lever modules. The separation and linkage mechanism is controlled by an electromagnet, resulting in a simple structure and control logic. When the retraction function is not needed, the attraction force between the first and second magnets is cleverly utilized to be greater than the electromagnet's attraction force, keeping the rotating bracket in an open state without affecting the reciprocating movement of the first slider lever module.

[0029] Please see Figures 1 to 10 The present invention provides a technical solution: a separable, linked reciprocating motion mechanism system, including a first slider lever module 100, a second slider lever module 200 and an electromagnet guide module 300;

[0030] The first slider lever module 100 includes a horizontal lever 1, a guide rail slider 2 and a guide rail 3. The guide rail 3 is fixedly installed on the machine body. The guide rail slider 2 is slidably connected to the guide rail 3. The first slider 5 is fixedly connected to the guide rail slider 2. The horizontal lever 1 is fixedly connected to the guide rail slider 2. The horizontal lever 1 is located at the top of the guide rail slider 2.

[0031] The second slider lever module 200 includes a return lever 7, a second slider 8, a flange bearing 9, a rotating bracket 10, a first magnet 11, and a tension spring 12. The second slider 8 is slidably connected to the guide rail 3. The return lever 7 is fixedly connected to the second slider 8 and is located at the top of the second slider 8. The inner side of the flange bearing 9 is fixedly connected to the second slider 8, and the outer side of the flange bearing 9 is fixedly connected to the rotating bracket 10. The first magnet 11 is fixedly connected to the second slider 8. One end of the tension spring 12 is fixedly connected to the first magnet 11, and the other end of the tension spring 12 is fixedly connected to the rotating bracket 10.

[0032] The electromagnet guiding module 300 includes a second magnet 16, a guide rod 13, an electromagnet mounting block 14, and an electromagnet 15. The first magnet 11 is attached to the second magnet 16, the second magnet 16 is located at the bottom of the first magnet 11, the electromagnet 15 is fixedly mounted on the electromagnet mounting block 14, and the guide rod 13 is fixedly connected to the electromagnet 15.

[0033] Furthermore, the first slider lever module 100 also includes a first slider 5 and a timing belt 4. The first slider 5 is fixedly connected to the guide rail slider 2, and the timing belt 4 is drivenly connected to the first slider 5.

[0034] Furthermore, the first slider lever module 100 also includes a timing belt pressure plate 6, which is fixedly connected to the first slider 5, and the timing belt 4 is located between the timing belt pressure plate 6 and the first slider 5.

[0035] Furthermore, the separable, linked reciprocating motion mechanism system also includes a drive unit module 400, which includes a motor 41 and a synchronous pulley 42. The motor 41 is fixedly mounted on the machine body, the synchronous pulley 42 is fixedly connected to the output end of the motor 41, and the synchronous belt 4 is drivenly connected to the synchronous pulley 42.

[0036] Furthermore, the second slider 8 is provided with a cylindrical boss 81, which is integrally formed with the second slider 8. The cylindrical boss 81 is engaged inside the flange bearing 9. The rotating seat 10 has a stepped hole 101, and the flange bearing 9 is engaged inside the stepped hole 101.

[0037] Furthermore, the electromagnet 15 is provided with an iron core 151, and the guide rod 13 has a mounting hole 131, with the iron core 151 engaging inside the mounting hole 131.

[0038] Furthermore, the guide rod 13 is provided with a positioning pin 132, which is fixedly connected to the guide rod 13, and the electromagnet mounting block 14 has a guide groove 141, with the positioning pin 132 located inside the guide groove 141.

[0039] Furthermore, the rotating bracket 10 is provided with a pin 102, which is fixedly connected to the rotating bracket 10. The first slider 5 has a through hole 51, and the pin 102 is engaged inside the through hole 51.

[0040] The horizontal lever 1 is fixed on the first slider 5, the first slider 5 is fixed on the guide rail slider 2, the guide rail slider 2 slides on the guide rail 3, and the synchronous belt pressure plate 6 presses the synchronous belt 4 onto the first slider 5. Under the drive of the motor 41 and the synchronous pulley 42, the synchronous belt 4 runs, driving the first slider 5 to move synchronously, thereby realizing the movement of the horizontal lever 1. The main function of the first slider lever module 100 is to push the test tube rack from the initial position of the tray to the end of the tray. The return lever 7 is fixed on the second slider 8, which is fastened to the guide rail slider 2. The flange bearing 9 is tightly fitted into the stepped hole 101 of the rotating bracket 10, pressing the rotating bracket 10 into the cylindrical boss 81 of the second slider 8, so that the rotating bracket 10 rotates around the cylindrical boss 81. The first magnet 11 is pressed into the round hole at the end of the second slider 8. The small round hole at the upper end of the second magnet 16 pressed into the second slider 8 and the small circle on the rotating bracket 10 are hooked by the small hooks at both ends of the tension spring 12. The main function of the second slider lever module 200 is to hook the first slider 5 and link it with the horizontal lever 1 assembly to push the test tube rack from the end of the tray to the beginning of the tray. Electromagnet 15 is mounted on electromagnet mounting block 14. A second magnet 16 is pressed into the upper circular hole of electromagnet mounting block 14. The second magnet 16 installed here attracts the first magnet 11 of the second slider lever module 200. The guide rod 13 is fixed to the iron core 151 with threaded end of electromagnet 15. The guide groove 141 of electromagnet mounting block 14 cooperates with the positioning pin 132 on guide rod 13, enabling guide rod 13 to achieve linear movement. The main functions of electromagnet guide module 300 are to fix electromagnet 15 and to move iron core 151 back and forth by switching electromagnet 15 on and off, thereby driving guide rod 13 to move back and forth. The positioning pin 132 at the other end of rotating bracket 10 is tangent to guide rod 13. The back and forth movement of guide rod 13 drives the rotation angle of rotating bracket 10 to change, thereby controlling the separation or linkage of transverse lever 1 assembly and return lever 7 assembly. The entire separation and linkage mechanism of this separable and linkage reciprocating return motion mechanism system is electrically controlled to realize return and continuous sample feeding.

[0041] Operating principle: such as Figure 8 and Figure 9The first slider lever module 100 is in the initial position of the tray (initial placement position of the test tube rack). During normal operation of the instrument, the first slider lever module 100 pushes the test tube rack from left to right in the initial position, pushing the samples one by one to the designated position for sampling puncture. After the samples are collected, the test tube rack is pushed to the end, and then another mechanism pushes the test tube rack out along the longitudinal position of the tray. The first slider lever module 100 then returns to the initial position. In normal sampling function, the position of the second slider lever module 200 remains unchanged and is not triggered. At this time, the horizontal lever 1 and the return lever 7 are in a separated state. Because the electromagnet guide module 300 and the second slider lever module 200 are respectively equipped with the first magnet 11 and the second magnet 16, the bottom of the first magnet 11 is surface A, and the top of the second magnet 16 is surface B. Surfaces A and B will attract each other, so that the first magnet 11 and the second magnet 16 attract each other, that is, the electromagnet guide module 300 and the second slider lever module 200 are attached together. Figure 10As shown, electromagnet 15 is not energized, guide rod 13 is in the initial position C1, and positioning pin 132 on rotating bracket 10 is tangent to guide rod 13. Rotating bracket 10 rotates around the protruding cylinder on the second slider 8 to a certain angle. During sampling, medical staff find that a certain set of data is abnormal and needs to be retested. They click the retest button, and the retest callback function is activated. When the test tube rack is pushed to the end, electromagnet 15 is energized, iron core 151 moves forward, driving guide rod 13 forward (positioning pin 132 of rotating bracket 10, which is tangent to guide rod 13, also separates and is no longer tangent). Due to the tension of spring 12, rotating bracket 10 rotates counterclockwise, and its end face presses against the first slider 5. Pin 102 on rotating bracket 10... Parallel to the through hole 51 on the first slider 5, the drive unit module 400 reverses the synchronous belt 4, and the first slider lever module 100 moves from the end to the initial end. The through hole on the first slider 5 fits the pin 102 of the rotating bracket 10. At this time, the transverse lever 1 and the second slider lever module 200 are connected together. The transverse lever 1 and the return lever 7 installed on the first slider 5 together hold the test tube rack, and together drive the test tube rack back to the designated position for resampling, achieving the purpose of retesting. After the retest sampling is completed, the electromagnet 15 is de-energized, the guide rod 13 returns to the initial position, and under the control of the drive unit module 400, the synchronous belt 4 drives the first slider lever module 100 to move to the end. The first slider 5 touches the second slider 8, and also pushes the second slider 8 to move synchronously. Correspondingly, it also pushes the test tube rack forward to the end of the tray. There is a gap between the two sliders that is larger than the pin 102. When pushing the second slider 8, the hooks between them are separated and not engaged. When pushed to the end position, due to the electromagnet guide module 300 and the second slider lever module 200, the first slider 5 touches the second slider 8, and also pushes the second slider 8 to move synchronously. Correspondingly, it also pushes the test tube rack forward to the end of the tray. There is a gap between the two sliders that is larger than the pin 102. When pushing the second slider 8, the hooks between them are separated and not engaged. When pushed to the end position, due to the electromagnet guide module 300 and the second slider 8, the first slider 5 touches the second slider 8, and the second slider 8 moves synchronously. Correspondingly, it pushes the test tube rack forward to the end of the tray. Because the block lever module 200 is equipped with the first magnet 11 and the second magnet 16 respectively, the first magnet 11 and the second magnet 16 attract each other, the electromagnet guide module 300 and the second slider lever module 200 are attached together, the guide rod 13 is tangent to the pin 102 of the rotating card seat 10, the rotating card seat 10 rotates clockwise and returns to the initial position, at this time the first slider lever module 100 and the second slider lever module 200 separate from each other, the first slider lever module 100 is controlled by the drive unit module 400 and returns to the initial position of the tray.

[0042] In addition, the separable and linked reciprocating motion mechanism system also has a continuous sample feeding mode. The continuous sample feeding mode is mostly used for multiple consecutive test tube racks. When the first test tube rack moves forward, the initial position leaves one test tube rack position vacant (before reaching the end position). The first slider lever module 100 can return to the initial position and move the second test tube rack that has just been pushed up at the initial position forward, so that the second test tube rack contacts the first test tube rack and pushes the first test tube rack to continue moving until the end position. The first slider lever module 100 can then return to the initial position again to advance the subsequent test tube racks in sequence, realizing continuous sample feeding, making the test samples more compact and improving efficiency.

[0043] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
