[0040] This application provides a microneedle testing module, which can be used in microneedle testing devices in practical applications. The microneedle testing module of this application will be described in detail below with reference to the accompanying drawings.

[0041] Reference Figures 1-7This application provides a microneedle testing module. The microneedle testing module has a first direction Z and specifically includes: a base 1, on which a positioning pin 11 is fixedly disposed; a mounting base 2, on which the positioning pin 11 extends along the first direction Z on the base 1, the positioning pin 11 including a first end and a second end disposed opposite to each other along the first direction Z, the diameter of the first end being a, and the diameter of the second end being b, a and b satisfying: 0.01mm≤a-b≤0.03mm, the diameter of the positioning pin 11 gradually decreasing from the first end to the second end; the mounting base 2 is detachably connected to the base 1, the mounting base 2 having a positioning hole 21; and a testing component 3, connected to the mounting base 2; wherein, when the mounting base 2 is connected to the base 1, the positioning pin 11 passes through the positioning hole 21, the shape of the positioning hole 21 being adapted to the shape of the positioning pin 11.

[0042] Specifically, such as Figures 1-4 As shown, the base 1 is used for fixed connection with the testing platform of the microneedle testing device. The positioning pin 11 can be fixedly set on the base 1 by welding, bonding or other methods.

[0043] Mounting base 2 is detachably connected to base 1, and test component 3 is connected to mounting base 2. Test component 3 can be used to connect to circuit board for micro-needle testing. By mounting base 2 to or removing it from base 1, test component 3 can be installed or replaced.

[0044] like Figure 4 As shown, the first direction Z is the Z-axis direction in the figure. The positioning pin 11 extends along the first direction Z on the base 1. The positioning pin 11 includes a first end and a second end that are arranged opposite to each other along the first direction Z. The first end is the bottom end of the positioning pin 11 along the first direction Z, and the diameter of the bottom end is a. The second end is the top end of the positioning pin 11 along the first direction Z, and the diameter of the top end is b. The diameter a of the first end of the positioning pin 11 can be greater than the diameter b of the second end, and the diameter of the positioning pin 11 gradually decreases from the first end to the second end, that is, the positioning pin is a tapered pin.

[0045] The mounting base 2 has a positioning hole 21 corresponding to the position of the positioning pin 11. The positioning hole 21 passes through the positioning pin 11 along the first direction Z. When the mounting base 2 is connected to the base 1, the positioning pin 11 passes through the positioning hole 21. The positioning pin 11 is a tapered pin. The shape of the positioning hole 21 is adapted to the shape of the positioning pin 11, that is, the shape of the positioning hole 21 is also tapered. When the mounting base 2 is installed on the base 1, the positioning pin 11 passes through the positioning hole 21 to achieve positioning of the mounting base 2.

[0046] When the difference between the diameter a of the first end and the diameter b of the second end is greater than 0.03 mm, the taper of the positioning pin 11 will be large, reducing the positioning accuracy of the positioning pin 11. When the difference between the diameter a of the first end and the diameter b of the second end is less than 0.01 mm, the positioning pin 11 will be difficult to insert into the positioning hole 21, increasing the assembly difficulty.

[0047] In this embodiment, by setting a positioning pin 11 on the base 1 and a corresponding positioning hole 21 on the mounting base 2, the diameter a of the first end and the diameter b of the second end of the positioning pin 11 satisfy: 0.01mm≤a-b≤0.03mm. In this way, during the installation of the mounting base 2, the positioning pin 11 can be easily inserted into the positioning hole 21, reducing the assembly difficulty of the mounting base 2. At the same time, the taper of the positioning pin 11 can be reduced, improving the positioning accuracy of the positioning pin 11. This can improve the stability of the mounting base 2 during installation, reduce the damage to the test component 3 caused by the positional deviation of the mounting base 2 or assembly difficulties, and thus reduce costs.

[0048] Optionally, a and b satisfy: ab = 0.01 mm. In practical applications, by making the diameter a of the first end and the diameter b of the second end 0.01 mm, the positioning pin 11 can be inserted into the positioning hole 21 more easily, and the taper of the positioning pin 11 can be further reduced, thereby improving the positioning accuracy of the positioning pin 11 and the stability of the mounting base 2 during installation. This further reduces the damage to the test component 3 caused by positional deviations or assembly difficulties of the mounting base 2, thus lowering costs.

[0049] In some optional embodiments, there are at least two positioning pins 11, which are spaced apart on the base 1; there are at least two positioning holes 21, with one positioning pin 11 corresponding to one positioning hole 21.

[0050] Specifically, such as Figure 2 As shown, both the base 1 and the mounting base 2 can be plate-like structures of any shape, such as rectangle or circle. This application embodiment does not make specific limitations on this. There are at least two positioning pins 11 and at least two positioning holes 21 on the mounting base 2. At least two positioning pins 11 are arranged at a certain distance on the base 1, and at least two positioning holes 21 are arranged at the same distance on the mounting base 2. When the mounting base 2 is connected to the base 1, one positioning pin 11 is inserted into one positioning hole 21.

[0051] In practical applications, by setting at least two positioning pins 11 and at least two positioning holes 21, the cooperation between multiple positioning pins 11 and multiple positioning holes 21 during the installation of the mounting base 2 can significantly improve the overall positioning accuracy, further improve the stability of the mounting base 2 during installation, and further reduce the damage to the test component 3 caused by positional deviation of the mounting base 2, thereby reducing costs.

[0052] In some alternative embodiments, at least two positioning pins 11 can be symmetrically arranged on both sides or around the base 1, and at least two corresponding positioning holes 21 can be symmetrically arranged on both sides or around the mounting base 2. This symmetrical layout can make the force on the mounting base 2 more evenly distributed during assembly, reduce the offset or deformation caused by excessive force on one side, further improve the stability of the mounting base 2 during installation, and further reduce the damage to the test component 3 caused by positional deviation of the mounting base 2, thereby reducing costs.

[0053] In some alternative embodiments, at least two positioning pins 11 may be asymmetrically spaced on the base 1, and at least two corresponding positioning holes 21 may also be asymmetrically positioned on the mounting base 2, which can be specifically set according to the actual situation.

[0054] For example, the number of positioning pins 11 and positioning holes 21 can be 2, 3, 4, etc., and can be selected according to the actual situation. This application embodiment does not make a specific limitation on this.

[0055] In some embodiments, at least one of the mounting base 2 and the base 1 is provided with a magnetic element 4, and one of the mounting base 2 and the base 1 is magnetically attracted to the other by the magnetic element 4.

[0056] Specifically, such as Figure 2 As shown, the magnetic component 4 can be disposed on the side of the mounting base 2 near the base 1, or the magnetic component 4 can be disposed on the side of the base 1 near the mounting base 2, or there can be two magnetic components 4, one disposed on the side of the mounting base 2 near the base 1 and the other disposed on the side of the base 1 near the mounting base 2. The magnetic component 4 can be a permanent magnet, and the magnetic component 4 can be disposed on the mounting base 2 and / or the base 1 by means of pasting, embedding, etc.

[0057] When the magnetic component 4 is located on the side of the mounting base 2 near the base 1, the base 1 is made of metal, and the mounting base 2 can be made of any material. The magnetic component 4 can magnetically attach the mounting base 2 to the base 1.

[0058] When the magnetic component 4 is located on the side of the base 1 near the mounting base 2, the mounting base 2 is made of metal, while the base 1 can be made of any material. The magnetic component 4 can magnetically attach the base 1 to the mounting base 2.

[0059] There can be two magnetic components 4. One is set on the side of the mounting base 2 near the base 1, and the other is set on the side of the base 1 near the mounting base 2. The base 1 and the mounting base 2 can be made of any material. By making the polarities of the two magnetic components 4 opposite, the base 1 can be magnetically attracted to the mounting base 2.

[0060] In this embodiment, by providing a magnetic element 4 in at least one of the mounting base 2 and the base 1, one of the mounting base 2 and the base 1 can be magnetically attracted to the other through the magnetic element 4. This facilitates the installation and removal of the mounting base 2, and consequently the installation and removal of the test component 3. It improves the efficiency of replacing the mounting base 2 and the test component 3, reduces the time spent by maintenance personnel replacing the mounting base 2, increases the speed of replacing the test component 3, reduces maintenance costs, and improves production efficiency.

[0061] In some alternative embodiments, there are multiple magnetic elements 4, which are spaced apart on the mounting base 2 and / or the base 1.

[0062] Specifically, such as Figure 2 As shown, there can be multiple magnetic elements 4, which are spaced apart on the mounting base 2 and / or the base 1. In this way, one of the mounting bases 2 is magnetically attracted to the other by multiple magnetic elements 4. The total magnetic attraction force generated by the combined action of multiple magnetic elements 4 is much greater than the magnetic attraction force of a single magnetic element 4, which can significantly enhance the connection strength between the mounting base 2 and the base 1, thereby effectively preventing the mounting base 2 from loosening or falling off and improving the installation stability of the mounting base 2 and the base 1.

[0063] For example, the magnetic component 4 can be 2, 3, 4, etc., and this application embodiment does not specifically limit it.

[0064] Optionally, one of the mounting base 2 and the base 1 is provided with a snap-fit, and the other is provided with a slot, with the snap-fit ​​engaging with the slot. In practical applications, by providing a snap-fit ​​in one of the mounting base 2 and the base 1, and the snap-fit ​​in the other, a detachable connection between the mounting base 2 and the base 1 is achieved. This facilitates the assembly and disassembly of the mounting base 2, and consequently the assembly and disassembly of the test component 3. This improves the efficiency of replacing the mounting base 2 and the test component 3, reduces the time spent by maintenance personnel replacing the mounting base 2, increases the speed of replacing the test component 3, reduces maintenance costs, and improves production efficiency.

[0065] In some alternative embodiments, the test assembly 3 includes: a floating plate 31, a needle holder 32, a plurality of microneedles 33, and an adapter plate 34; the adapter plate 34 is fixedly connected to the side of the mounting base 2 near the base 1; the floating plate 31 is movably disposed on the side of the mounting base 2 away from the base 1; the needle holder 32 is disposed within the mounting base 2; the microneedles 33 are connected to the adapter plate 34, and the microneedles 33 pass through the needle holder 32 and the floating plate 31.

[0066] Specifically, such as Figures 1-3 , Figure 5 As shown, the adapter plate 34 can be fixedly connected to the side of the mounting base 2 near the base 1 by the second fastener 38. Furthermore, the second fastener 38 can be a bolt.

[0067] The floating plate 31 is movably disposed on the side of the mounting base 2 away from the base 1, so that the floating plate 31 can move closer to or further away from the mounting base 2.

[0068] The mounting base 2 is provided with a mounting groove, which is adapted to the shape and size of the needle holder 32. The needle holder 32 is set in the mounting groove. One end of a plurality of micro needles 33 is fixedly connected to the adapter plate 34. The needle holder 32 is provided with a plurality of needle holes, and the floating plate 31 is provided with a plurality of needle grooves. Each needle hole is aligned with each needle groove. The other end of each micro needle 33 passes through each needle hole and each needle groove in sequence.

[0069] In practical applications, during microneedle testing, by bringing the floating plate 31 close to the mounting base 2, the microneedle 33 passes through the needle groove and contacts the test point on the circuit board, transmitting signals to the adapter board 34. The adapter board 34 connects the microneedle 33 to other external devices, serving as a signal transmission and interface conversion tool, ensuring accurate transmission of test signals to external devices. After testing, the floating plate 31 is moved away from the mounting base 2, with the microneedle 33 located inside the floating plate 31. The floating plate 31 protects the microneedle 33, reducing the risk of oxidation, impacts, and other problems.

[0070] It should be noted that the specific structures of the floating plate 31, the needle holder 32, the multiple microneedles 33 and the adapter plate 34 can refer to the prior art, and the embodiments of this application do not specifically limit them.

[0071] Optionally, the test assembly 3 also includes a plurality of first fasteners 35, and the floating plate 31 is provided with a plurality of mounting holes 310, with one first fastener 35 passing through one mounting hole 310 and being fixedly connected to the mounting base 2.

[0072] Specifically, such as Figure 2 and Figure 6 As shown, the first fixing member 35 is a connecting bolt, and the floating plate 31 is provided with a mounting hole 310. The first fixing member 35 can pass through the mounting hole 310 and be threadedly connected to the mounting base 2. The diameter of the mounting hole 310 is larger than the diameter of the first fixing member 35. The first fixing member 35 can provide a guiding function for the movement of the floating plate 31, so that the floating plate 31 can move closer to or away from the mounting base 2 on the first fixing member 35.

[0073] In practical applications, the first fixing member 35 passes through the mounting hole 310 and is fixedly connected to the mounting base 2. The first fixing member 35 can provide guidance for the movement of the floating plate 31, so that the floating plate 31 can move closer to or away from the mounting base 2, which can reduce the offset of the floating plate 31 and reduce the damage to the micro needle 33, thus reducing costs.

[0074] For example, the first fastener 35 and the mounting holes 310 can be 2, 3, 4, etc., and this application embodiment does not specifically limit them.

[0075] Optionally, it also includes a plurality of elastic elements 36, with the floating plate 31 and the mounting base 2 spaced apart, and the elastic elements 36 disposed between the floating plate 31 and the mounting base 2.

[0076] Specifically, such as Figure 2 and Figure 7 As shown, the elastic element 36 can be a spring, the floating plate 31 and the mounting base 2 are spaced apart, one end of the elastic element 36 is disposed in the mounting base 2, and the other end extends out of the mounting base 2 and is connected to the floating plate 31;

[0077] In practical applications, by setting multiple elastic elements 36, when microneedle testing is required, pressing the floating plate 31 causes the floating plate 31 to approach the mounting base 2, and the floating plate 31 compresses the elastic elements 36, causing the elastic elements 36 to generate elastic force. After the test is completed, under the action of the elastic force, the floating plate 31 quickly returns to its initial position.

[0078] For example, there may be 2, 3, 4, etc., and this application does not specifically limit this.

[0079] In some alternative embodiments, the mounting base 2 may also be provided with a plurality of guide posts 37, and the floating plate 31 is provided with a plurality of guide holes. The guide posts 37 pass through the guide holes. The movement of the floating plate 31 can be guided by the guide posts 37, which can reduce the offset of the floating plate 31 and the damage to the micro needles 33, and reduce costs.

[0080] In some alternative embodiments, the adapter plate 34 may be provided with a buckle that engages with the base 1 to stabilize the test platform. Since long-term use of the positioning pin 11 for positioning can affect the positioning accuracy of the positioning pin 11, by setting a buckle on the micro-needle adapter plate to stabilize the test platform, the impact of the positioning gap of the positioning pin 11 can be reduced, thereby improving the pass rate of functional testing.

[0081] In summary, the microneedle testing module described in this application embodiment has at least the following advantages:

[0082] In this embodiment, by setting a positioning pin 11 on the base 1 and a corresponding positioning hole 21 on the mounting base 2, the diameter a of the first end and the diameter b of the second end of the positioning pin 11 satisfy: 0.01mm≤a-b≤0.03mm. In this way, during the installation of the mounting base 2, the positioning pin 11 can be easily inserted into the positioning hole 21, reducing the assembly difficulty of the mounting base 2. At the same time, the taper of the positioning pin 11 can be reduced, improving the positioning accuracy of the positioning pin 11. This can improve the stability of the mounting base 2 during installation, reduce the damage to the test component 3 caused by the positional deviation of the mounting base 2 or assembly difficulties, and thus reduce costs.

[0083] This application also provides a microneedle testing device, which may specifically include the microneedle testing module described in any of the above embodiments.

[0084] It should be noted that in this embodiment, the structure of the microneedle testing module is the same as that of the microneedle testing module in any of the above embodiments, and its beneficial effects are similar, so it will not be described in detail here.
