[0035] In the technical solution, the reagent strip transfer assembly is arranged, and the electric clamping jaw 21 thereof can realize the mechanization and automation of placing and transferring the reagent strips 31 into the reagent strip loading section, so that manual processing is no longer needed, the labor cost is reduced, and the efficiency of the reagent strip post-processing process is improved.

[0036] In some embodiments, the reagent strip transfer assembly further comprises: a support 22, which serves as a bearing structure, the support 22 is assembled with a first linear guide rail 23 and a first translation driving assembly 24; a lifting driving assembly 25, which is assembled with the electric clamping jaw 21, the lifting driving assembly 25 is drivingly connected with the first translation driving assembly 24 and is slidingly connected with the first linear guide rail 23, in this way, the horizontal position and the height position of the electric clamping jaw 21 are adjusted through the first translation driving assembly 24 and the lifting driving assembly 25, so as to realize stable and reliable clamping and transferring of the reagent strips 31. Figure 1As shown, the first translation driving assembly 24 specifically includes a second rotary motor 242 fixedly assembled on the support 22, and a belt pulley 243 is sleeved on the output shaft of the second rotary motor 242, while a corresponding belt pulley (not shown in the figure) is also provided on the lifting driving assembly 25, and a belt 241 is tensioned between the two belt pulleys, so as to realize the purpose of converting the circumferential displacement of the second rotary motor 242 into the horizontal linear displacement of the lifting driving assembly 25, and at the same time, since the lifting driving assembly is connected with the electric clamping jaw 21 as a whole, the linear reciprocating adjustment of the horizontal position of the electric clamping jaw 21 is realized. The lifting driving assembly 25 can be a market electric telescopic rod and the like capable of lifting, and will not be described here.

[0037] The electric clamping jaw 21 can be a market electric clamping jaw with appropriate specifications, and in a preferred embodiment, the electric clamping jaw 21 includes multiple groups of parallel clamping jaws, so as to realize the clamping and transfer of multiple reagent strips 31 at one time, and further improve the work efficiency.

[0038] The reagent strip assembly includes a reagent strip holder 32, and multiple reagent strips 31 are arranged on the reagent strip holder 32. The support 22 is provided with a reagent strip holder anti-uplift plate 221, which can limit the upward displacement of the reagent strip holder 32, so that the reagent strip holder 32 will not be lifted when the electric clamping jaw 21 clamps the reagent strips 31 thereon, and remains in the original area, thereby ensuring the smooth transfer of the reagent strips 31.

[0039] The first reciprocating pushing assembly includes a pushing plate 41 in the reagent strip loading section, a first rotary motor 42 with a gear on the output shaft, a rack 43 and a second linear guide rail 44 arranged in parallel and spaced apart, which are arranged on the groove wall of the first linear moving guide groove 1, the gear is engaged with the rack 43, the first rotary motor 42 is fixedly connected with the pushing plate 41 and the first rotary motor 42 is slidingly connected with the second linear guide rail 44. In this technical solution, the rotary drive of the first rotary motor 42 is converted into linear motion due to the engagement of the gear and the rack 43. Specifically, since the rack 43 is fixedly connected with the groove wall, the first rotary motor 42 will move linearly with the pushing plate 41 fixedly connected therewith. It is particularly emphasized that in this technical solution, such a linear driving mode can ensure the reliable movement of the numerous reagent strips 31 in the first linear guide groove 1. Generally, during the operation of the device of the present application, the reagent strips 31 in the guide groove will almost fill the full length of the groove body at the beginning, and this obviously requires a more reliable and sufficient driving force pushing assembly.

[0040] In a preferred embodiment, the first linear movement guide groove 1 is provided with a code printing bin 51 at a region corresponding to the code printing assembly, and the code printing assembly can specifically adopt a laser code printing gun. The code printing bin 51 can form a physical isolation for the spraying material of the code printing assembly, so as to prevent the code printing material from overflowing to the external environment and causing pollution. The end position of the reagent strip pushing section is provided with a travel switch 52, which is used to detect whether the reagent strip 31 in the first linear movement guide groove 1 reaches a preset position, and give a feedback signal when reaching the preset position to realize code printing on the reagent strip at the code printing bin 51. That is, the travel switch 52 serves as a detection component for the reagent strip 31 reaching the code printing region, and can form linkage with the control component of the device to finally realize accurate control of the code printing action of the code printing assembly by the control component.

[0041] Referring to Figure 2 As shown in the figure, the reagent strip post-processing device further comprises: a second linear movement guide groove 5, which is arranged in parallel with the first linear movement guide groove 1 and is arranged adjacent to the first linear movement guide groove 1; a second reciprocating pushing assembly 53, which is perpendicular to the extension direction of the first linear movement guide groove 1, so as to push the reagent strip 31 in the reagent strip pushing section into the second linear movement guide groove 5; and a two-dimensional code quality inspection scanning assembly, which comprises a scanning module 61 and is used to scan the two-dimensional code printed on the reagent strip 31 in its scanning region. Through the non-collinear arrangement between the second linear movement guide groove 5 and the first linear movement guide groove 1, the layout of each component can be more reasonable and compact, and the overall space of the device is optimized. Through the two-dimensional code quality inspection scanning assembly, the two-dimensional code sprayed by the code printing assembly upstream can be identified and verified, so as to ensure the code printing quality of the reagent strip 31 and effectively improve the product quality. It can be understood that the reagent strip 31 that cannot be identified by the two-dimensional code quality inspection scanning assembly is a reagent strip with unqualified quality, and the reagent strip that can be identified is a qualified reagent strip. In addition, it should be noted that the scanning module 61 of the two-dimensional code quality inspection scanning assembly and the corresponding processing component are prior art in the industry in terms of functional implementation, and their specific structure, construction and implementation mode are not intended to be protected by the present application. The present application intends to integrate them into the device of the present application, thereby realizing functional integration and improving the multifunction and efficiency of the reagent strip post-processing device.

[0042] Specifically, referring to Figure 2 As shown in the figure, the two-dimensional code quality inspection scanning assembly further comprises: a scanning module support 62, on which at least two scanning modules 61 are arranged at intervals along the guide direction of the second linear movement guide groove 5; and a second translation driving assembly 63, which is connected with the scanning module support 62 to drive the scanning module support 62 to move linearly and reciprocally along the guide direction of the second linear movement guide groove 5. Figure 2As an example, the scanning module 61 in the present application is provided with two, which can be adjusted by the position change of the second translation driving assembly 63 (including the initial position, and adjusting the position twice can be realized) to realize the two-dimensional code scanning of a group of six reagent strips 31 by two scanning modules 61, without the need for six reagent strips 31 to correspond to one scanning module 61 respectively, saving the manufacturing cost. The second translation driving assembly 63 and the first translation driving assembly 24 can adopt the same design in terms of implementation principle and structure, which will not be described here.

[0043] The first end of the second linear movement guide groove 5, that is, the end corresponding to the reagent strip pushing-out section, is provided with a third reciprocating pushing assembly 9, which can reciprocate linearly along the guide direction of the second linear movement guide groove 5 by a second preset distance, so that each reagent strip 31 can form a flow transmission along the guide direction of the second linear movement guide groove 5.

[0044] A rejection assembly is also provided in the downstream area of the two-dimensional code inspection scanning assembly, which can remove the waste reagent strips identified by the two-dimensional code inspection scanning assembly from the reagent strip sequence, thereby realizing the final quality control of the reagent strips 31. Specifically, the rejection assembly includes a cylinder 71 with a controllable telescopic push rod, which is perpendicular to the guide direction of the second linear movement guide groove 5. When the two-dimensional code inspection scanning assembly identifies an unqualified reagent strip 31, the push rod of the cylinder 71 at the corresponding position will be controlled to extend when the unqualified reagent strip 31 is transmitted to the corresponding position, thereby pushing the unqualified reagent strip 31 out of the second linear movement guide groove 5. A waste box is provided at the corresponding position to collect these unqualified reagent strips 31. Specifically, the position of the waste box is set in the downstream area of the reagent strip pushing-out section and the area on the side of the second linear movement guide groove 5 facing the first linear movement guide groove 1.

[0045] In a preferred embodiment, the rejection assembly further includes an electromagnetic clamping assembly 72, which is provided correspondingly with the cylinder 71 and has a clamping state of forming clamping positioning on the reagent strip 31 and a disengagement state of releasing the clamping positioning on the reagent strip 31. The electromagnetic clamping assembly 72 is in the disengagement state when the push rod of the cylinder 71 extends, and in the clamping state when the push rod of the cylinder 71 retracts, which can form reliable positioning of the qualified reagent strips 31 during the rejection process of the cylinder 71, preventing the adjacent qualified reagent strips 31 from being taken away during the rejection of the unqualified reagent strips 31. For example, Figure 2As shown, the electromagnetic clamping assemblies 72 and the air cylinders 71 are respectively provided in plurality and one-to-one correspondence. The electromagnetic clamping assembly 72 has, for example, an electromagnetic push rod, linear motion of the electromagnetic push rod is controlled by the attractive force or repulsive force of an electromagnet, and is also controlled by a spring provided in correspondence therewith. Normally, the electromagnetic push rod is in a disengaged state to ensure normal flow transmission of the reagent strips 31. At this time, the electromagnet is in a de-energized state. When it is necessary to reject, the electromagnet corresponding to the qualified reagent strip 31 is energized to make the electromagnetic push rod in a clamped state, and the electromagnet corresponding to the unqualified reagent strip 31 is maintained in a de-energized state to make the electromagnetic push rod remain in a disengaged state, thereby facilitating the rejection of the unqualified reagent strip 31 from the queue.

[0046] The second linear movement guide groove 5 has a reagent strip collection plate 8 downstream of the reagent strip guide movement direction therein to collect the qualified reagent strip 31 therein.

[0048] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
