Technical Field
[0001] The utility model relates to the field of consumables detection in the field of in vitro diagnosis, and in particular to an IVD consumables adaptation mechanical detection tooling. Background Art
[0002] Consumables used in the in vitro diagnostic field are diverse and consumed in high volumes. Common consumables include PCR tubes, tips, PCR caps, and the adapters used to remove these consumables. Frequent removal and removal are often required, and pipetting or transferring liquids requires the use of adapters. A reliable connection between the adapter and the consumables is crucial to prevent dripping or dropping. Therefore, mechanical testing of the removal and removal of tips, PCR tubes, and PCR caps is often required during R&D. Currently, manual testing is typically performed for the removal and removal of these consumables, using push-pull force gauges and pressure sensors to determine the external force required to remove the consumable from the adapter and the force required to remove the consumable. This testing method is subject to significant human error, cannot guarantee the proper fit between the adapter and the consumable, results in significant errors, and requires multiple tests, resulting in low testing efficiency. Furthermore, testing is generally performed on diagnostic equipment, which has a small operating space and is inconvenient, further reducing testing efficiency. Therefore, the design of highly accurate and efficient mechanical testing tooling is crucial. Summary of the Invention
[0003] In view of this, the utility model proposes an IVD consumables adaptation mechanical testing tooling, which realizes automatic testing and improves the testing efficiency of IVD consumables.

DETAILED DESCRIPTION
[0017] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.
[0018] It should be noted that, in the description of the present utility model, relational terms such as "first" and "second" are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
[0019] In the description of this utility model, unless otherwise specified or limited, the terms "connected" and "connection" that may appear should be understood in a broad sense. For example, it can mean fixed connection, detachable connection, or integral connection; it can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediate medium, or it can mean internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood based on specific circumstances.
[0020] like Figure 1-2 As shown, the IVD consumables adaptation mechanical testing tooling described in the present invention includes an electric control box 1, a first mounting member (i.e., a horizontally arranged first mounting plate 2), a second mounting member, a monitoring unit, a positioning member arranged on the first mounting plate 2 (the positioning member is a vertically arranged positioning frame 3, and a consumables pool for positioning the consumables is fixed on the top of the positioning frame 3) and a lifting mechanism arranged above the positioning frame 3; during actual installation, the first mounting plate 2 is horizontally installed on the top of the electric control box 1 to save space; the second mounting member is a second mounting plate 4 with its bottom fixed on the first mounting plate 2 (of course, the second mounting member can also be replaced by a column and a plate fixed on the column), and the second mounting plate 4 is arranged vertically;
[0021] The lifting mechanism includes a power source disposed above the second mounting plate 4 and a lifting member (i.e., a lifting seat 5) driven by the power source. A connecting member (i.e., a connecting block) for securing the adapter F1 is disposed below the lifting seat 5. The connecting block has a mounting hole that mates with the adapter F1, and the top of the adapter F1 can be snapped into the mounting hole.
[0022] A baffle (i.e., baffle 6) is horizontally disposed in the middle of the second mounting plate 4 for ejecting consumables. A through slot is defined at the end of baffle 6 for the adapter F1 to pass through. During the upward movement, the adapter F1 passes smoothly through the through slot, while consumables at the bottom of the adapter F1 cannot pass through, thereby enabling the automatic ejection of the tip, PCR tube, or PCR cap.
[0023] The monitoring unit includes a controller and a pressure sensor 7 for monitoring the fit between adapter F1 and the consumable. The pressure sensor's signal output is connected to the controller's signal input, and the controller's control output is connected to the power source's control input. During testing, the controller raises and lowers the power source, and the pressure sensor 7 transmits a pressure signal to the controller, which then determines the fit between the adapter and the consumable.
[0024] During actual operation, the top of the adapter F1 is inserted into the connecting block, the consumable pool (such as TIP pool, PCR tube pool and PCR cap pool) is fixed on the top of the positioning frame 3, and the consumables are inserted into the consumable pool; the power source drives the adapter F1 down through the lifting seat 5, so that its bottom is adapted and inserted into the consumables below. During this process, the pressure sensor 7 monitors the adaptation force between the adapter F1 and the consumables in real time; when rising, the adapter F1 can pass through the baffle 6 and the consumables are withdrawn under the reverse force of the baffle 6, thereby realizing the return of the parts.
[0025] During the lifting and lowering process of the power source, the present invention can also determine the adaptation effect under different strokes and speeds by changing the movement stroke and descending speed of the power source, thereby providing basic operating data for the in vitro diagnostic instrument.
[0026] Combine Figure 1 As can be seen, an origin sensor 8 is mounted on the upper portion of the second mounting plate 4. This sensor is preferably a photoelectric switch. A trigger element (i.e., a metal trigger piece 9) is provided on the lift base 5 to trigger the photoelectric switch. The signal output of the origin sensor 8 is connected to the signal input of the controller. When the trigger piece 9 moves into the groove of the photoelectric switch, the photoelectric switch is triggered, indicating that the lift base 5 is at its origin.
[0027] During actual installation, the pressure sensor 7 is installed between the lifting seat 5 and the connecting block to monitor the adaption force between the adapter F1 and the consumables. Of course, the pressure sensor 7 can also be installed at the bottom of the positioning frame 3.
[0028] During actual installation, in order to further ensure the adaptation effect between the adapter and the consumables, the monitoring unit also includes an adaptation monitoring component for monitoring the adaptation of the adapter and the consumables, and the signal output end of the adaptation monitoring component is connected to the signal input end of the controller. Among them, the adaptation monitoring component can be a displacement sensor 10 installed on the second mounting plate 4, which can directly monitor the downward displacement of the adapter, thereby ensuring the adaptation effect between the adapter and the consumables, reducing errors, and improving the accuracy of the detection results. Of course, during actual installation, the adaptation monitoring component can also be an encoder, which uses the encoder to detect the motor position signal to unify the adaptation effect of the adapter F1 and the consumables.
[0029] Combine Figure 1As can be seen, the power source of the present invention is a screw transmission mechanism, which includes a stepper motor 11, a screw 12 driven by the stepper motor 11, and a nut seat threadedly connected to the screw 12. The lifting seat 5 is fixed to the nut seat, and the stepper motor 11 is fixed to the upper part of the second mounting plate 4 through the motor seat. Of course, in actual installation, the power source can also be a synchronous belt transmission mechanism, a cylinder, a hydraulic cylinder, or an electric push rod;
[0030] Combine Figure 1 As can be seen, the lifter is connected to the second mounting member via a guide pair. This guide pair is a rail-slider pair, comprising a rail 13 secured to the second mounting plate 4 and a slider 14 secured to the bottom of the lifter 5. Slider 14 is slidably mounted on rail 13, effectively preventing the lifter 5 from twisting during the lifting process and ensuring the lifter's motion accuracy. Of course, in actual installation, the guide pair can also be column-guided, with a guide column mounted on the second mounting plate 4 and a guide sleeve mounted on the lifter 5 to mate with the guide column.
[0031] During installation, baffle 6 is screwed to the second mounting plate 4 located below the slide rail 13. The slot in baffle 6 aligns with the adapter F1, ensuring smooth insertion of the adapter F1. To accommodate different adapter F1 models, the slot in baffle 6 can be machined to various specifications to facilitate smooth insertion. During actual testing, the matching baffle 6 can be selected based on the adapter F1 model.
[0032] The utility model can be used for mechanical testing between consumables such as TIP, PCR tube or PCR cap and their matching adapters. During the test, the consumable pool matching these consumables to be tested needs to be installed on the positioning frame to position the consumables. Figure 3-Figure 4 Taking the inspection of a TIP and its adapter as an example, during the inspection, the TIP pool is mounted on the positioning frame 3, the TIP that matches the TIP pool is inserted into the TIP pool, and the adapter F1 that matches the TIP to be inspected is mounted on the connecting block. A suitable baffle 6 is selected and installed below the slide rail 13 to ensure that the adapter F1 passes smoothly. The adapter F1 is driven down by the stepper motor 11 so that its bottom is inserted into the TIP below. The adapter F1 is then driven up by the stepper motor 11, and the TIP is retracted using the baffle 6, thereby achieving mechanical inspection between the TIP and its adapter.
[0033] It should be noted that the controller in this embodiment can be a general-purpose processor, a dedicated processor, a conventional processor, a digital signal processor (DSP), multiple microprocessors, one or more microprocessors associated with a DSP core, a controller, a microcontroller, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) circuit, any other type of integrated circuit (IC), a state machine, etc. It can also be a programmable logic controller or an industrial computer. Furthermore, the controller can also be equipped with a wireless communication module to connect to a remote terminal, receive control commands from the remote terminal, and provide feedback on parameters related to the real-time operating status.
[0034] Finally, it should be emphasized that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
