[0027] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0028] like Figure 1 As shown, the utility model provides an auxiliary tool for the production of chromatography test strips, including a base 100 and a baffle, wherein the base 100 is used to place a PVC bottom plate, and the baffle is used to limit the PVC bottom plate.
[0029] In some embodiments of the present invention, the cross-sectional shape of the base 100 may be rectangular or other polygonal, or may be any shape such as circular or elliptical, and is preferably the same shape as the PVC base plate to make operation more convenient and efficient.
[0030] In the following embodiments of the present invention, the cross-sectional shape of the base 100 is assumed to be a rectangle.
[0031] In some embodiments of the utility model, the baffle includes a first baffle 200 and a second baffle 300, and the first baffle 200 and the second baffle 300 are formed to extend in parallel along a first direction. At least one of the first baffle 200 and the second baffle 300 is detachably arranged on the base 100 and the position on the base 100 can be adjusted along a second direction. The first direction and the second direction are perpendicular to each other, wherein the first direction can be understood as the length direction of the base 100, and the second direction can be understood as the width direction of the base 100.
[0032] In the present invention, the first baffle 200 and the second baffle 300 are both raised structures relative to the base 100, and are mainly used to limit and align when pasting paper strips, so as to ensure the accuracy of the pasting position.
[0033] Optional, such as Figure 2As shown, the first baffle 200 is fixedly arranged on one side of the base 100, and the position of the second baffle 300 on the base 100 can be adjusted along the second direction. By moving the second baffle 300, the PVC bottom plate of different sizes can be limited between the first baffle 200 and the second baffle 300. When two paper strips need to be pasted on the PVC bottom plate, the two paper strips are pasted on the PVC bottom plate along the edges of the first baffle 200 and the second baffle 300 respectively; when three paper strips need to be pasted on the PVC bottom plate, one side of the PVC bottom plate can be abutted against the first baffle 200, and the other side can be pressed and fixed by moving the second baffle 300. At this time, paper strips can be pasted along the edges on both sides of the second baffle 300 and the inner edge of the first baffle 200 respectively; when more paper strips need to be pasted on the PVC bottom plate, it is only necessary to continue to move the position of the second baffle 300.
[0034] Optionally, the positions of the first baffle 200 and the second baffle 300 on the base 100 can be adjusted along the second direction. In this case, when it is necessary to stick a paper strip on the PVC bottom plate, the operation is the same as above. The only difference is that the first baffle 200 can be fixed at a certain position or the PVC bottom plate can be pressed and fixed to facilitate sticking of the paper strip, which will not be elaborated herein.
[0035] In some embodiments of the present invention, the baffle further includes a third baffle 400 disposed along the first direction, the third baffle 400 is installed between the first baffle 200 and the second baffle 300, and the position of the third baffle 400 on the base 100 can be adjusted along the second direction.
[0036] Optionally, the first baffle 200 is fixedly disposed on one side of the base 100, and the position of the second baffle 300 on the base 100 can be adjusted along the second direction. By moving the second baffle 300, the PVC base plates of different sizes can be limited between the first baffle 200 and the second baffle 300, and the third baffle 400 is pressed on the adhesive surface of the PVC baffle. The pasting position of different paper strips is determined by adjusting the position of the third baffle 400. For example, when it is necessary to paste a gold pad / fluorescent pad, a sample pad, or absorbent paper on the PVC base plate, first limit the PVC base plate between the first baffle 200 and the second baffle 300, press the third baffle 400 on a suitable position on the PVC base plate, quickly paste the gold pad / fluorescent pad on the PVC base plate along the edge of the third baffle 400 close to the second baffle 300, continue to quickly paste the sample pad on the PVC base plate along the inner edge of the second baffle 300, then remove the third baffle 400, and quickly paste the absorbent paper on the PVC base plate along the inner edge of the first baffle 200.
[0037] It is understandable that, since the paper strips are pasted along the edge of the baffle during the entire operation, and each baffle is adjusted to a suitable position in advance according to actual conditions, the entire process can be completed quickly, effectively improving production efficiency and product consistency, thereby effectively reducing the CV value.
[0038] In some embodiments of the present invention, a scale 500 is further included. The scale 500 is disposed on the mounting surface of the base 100 along the second direction.
[0039] Optionally, a ruler 500 is installed between the ends on the same side of the first baffle 200 and the second baffle 300, and the ruler 500 is installed at both ends. The third baffle 400 can adjust its position according to the ruler 500, and by setting the ruler 500 at both ends, the position of the third baffle 400 can be better limited so that it is in a parallel state, thereby avoiding tilting during the paper strip pasting process and affecting accuracy.
[0040] In some embodiments of the present invention, a first limiting assembly and a second limiting assembly are further included, the first baffle 200 and / or the second baffle 300 are fixed to the base 100 via the first limiting assembly, and the third baffle 400 is fixed to the base 100 via the second limiting assembly.
[0041] Optional, such as Figure 5 As shown, the first limiting assembly includes a first mounting groove 610 and a first fixing plate 620, and the first fixing plate 620 is installed in the first mounting groove 610; the first mounting groove 610 is opened along the second direction, and the first mounting groove 610 is opened on the lower surface of the base 100; when the position of the first baffle 200 on the base 100 is adjustable, the first baffle 200 is fixed to the base 100 through the first limiting assembly, at this time, the screws pass through the first baffle 200, the first mounting groove 610 and the first fixing plate 620 in sequence, thereby realizing the fixing and limiting of the first baffle; when the position of the second baffle 300 on the base 100 is adjustable, the second baffle 300 is fixed to the base 100 through the first limiting assembly, at this time, the screws pass through the second baffle 300, the first mounting groove 610 and the first fixing plate 620 in sequence, thereby realizing the fixing and limiting of the second 300 baffle.
[0042] After the screw passes through the first baffle 200 or the second baffle 300, the first installation groove 610 and the first fixing plate 620 in sequence, the first baffle 200 or the second baffle 300 is limited. When the position of the first baffle 200 and / or the second baffle 300 needs to be adjusted, it is only necessary to loosen the screw to move it to the corresponding position. Similarly, when the first baffle 200 and / or the second baffle 300 needs to be fixed, it is only necessary to tighten the screw, which is simple and convenient to operate.
[0043] Optional, such as Figure 3-4As shown, a first mounting groove 610 is also provided on the upper surface of the base 100, through which the first mounting groove 610 on the upper surface can be used to facilitate the movement of the first baffle 200 and / or the second baffle 300; and the length of the first mounting groove 610 can be actually adjusted according to the width of the PVC base plate, and there is no special limitation on this. For example, the commonly used specifications of PVC base plates are 8 cm and 6 cm. Therefore, the distance between the first baffle 200 and the second baffle 300 can be adjusted to 8 cm or 6 cm by adjusting the first limit assembly.
[0044] Optional, such as Figure 6 As shown, the second limiting assembly includes a second mounting groove 710, a limiting plate 720 and a second fixing plate 730, and the limiting plate 720 and the second fixing plate 730 are both installed in the second mounting groove 710; the second mounting groove 710 is opened along the second direction, and the second mounting groove 710 is respectively opened on the upper and lower surfaces of the base 100; the screws pass through the limiting plate 720, the second mounting groove 710 and the second fixing plate 730 in sequence to form a limiting member, and the third baffle 400 is installed between the two limiting members.
[0045] Optionally, the length of the second mounting groove 710 is greater than the width of the PVC bottom plate, so that the third baffle 400 can be moved within the width of the PVC bottom plate to accommodate the rapid pasting of the paper strip at any position.
[0046] It can be understood that two limit members form a group to limit one end of the third baffle 400. The position of the limit member relative to the base 100 and the distance between the two limit members can be adjusted by loosening or tightening the screws. The position of the third baffle 400 can be moved by adjusting the position of the limit member relative to the base 100, and the distance between the two limit members can be adjusted to adapt to third baffles 400 of different widths and limit the third baffle 400, so as to avoid position displacement during the pasting process and affect the position accuracy of the pasting.
[0047] In some embodiments of the present invention, the lengths of the first baffle 200 and the second baffle 300 are equal, and the length of the third baffle 400 is greater than the lengths of the first baffle 200 and the second baffle 300, so that the third baffle 400 can be taken and placed without affecting the chromatography test strip.
[0048] Optionally, operating parts 110 are provided at both ends of the base 100 to facilitate the movement of the base 100 as a whole and enhance operability.
[0049] In summary, by using this auxiliary tool, the paper strips to be pasted can be effectively limited to the position where they need to be pasted, and the position where each paper strip needs to be pasted can be adjusted in advance by moving the baffle, which is suitable for different projects where the paper strips have different sizes and pasting positions; and it can effectively reduce the problem of inconsistent overlapping widths of the paper strips carrying each component when manually pasting the paper strips, thereby achieving consistency in pasting the paper strips and increasing the pasting speed, greatly improving production efficiency and reducing the CV value of the product.
[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
