Description

Technical Field

[0001] The utility model relates to the technical field of the installation of the upper flow path board of a nuclide synthesizer, in particular to a flow path board positioning device. Background Art

[0002] The flow path board plays a key role in the synthesis of radioactive drugs or isotopes by a multi-nuclide multi-functional synthesizer. Its main functions include: guiding the flow of fluids, reacting mixtures, controlling the flow rate and flow volume, separating and purifying, as well as protecting and ensuring safety.

[0003] Before using the multi-functional synthesizer, the flow path board needs to be installed on its top cover. For example, in the utility model patent application No. 201921218422.0, titled "A Device for Fixing an Integrated Flow Path Board", it includes a body which is composed of a first pressing strip, a second pressing strip, a third pressing strip, and a fourth pressing strip. The first pressing strip, the second pressing strip, the third pressing strip, and the fourth pressing strip are connected end to end. By the way of the end-to-end buckling connection of the first pressing strip, the second pressing strip, the third pressing strip, and the fourth pressing strip, the integrated flow path board is surrounded. The two sides of the integrated flow path board are respectively contacted and pressed by the first step and the second step, so that the integrated flow path board is in full contact with the bottom plate of the synthesizer. Through the cooperation and tightening of the through holes on each pressing strip and the screws, the integrated flow path board is well fixed on the bottom plate of the synthesizer. In essence, the four pressing strips press the four sides of the flow path board against the top plate, and then the installation holes below the flow path board are connected to the top plate with screws. However, in the actual installation process, it is found that: there are differences in the distances between the flow path board and the first pressing strip, the second pressing strip, the third pressing strip, and the fourth pressing strip, or the phenomenon of being installed reversely occurs, resulting in the difficulty of installing the flow path board at the geometric position of the target area and the difficulty of meeting the working requirements.

[0004] Therefore, there are differences or reverse installation between the existing body and the flow path board, which makes it difficult to meet the working requirements. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a flow path board positioning device, which drives a positioning component through a pneumatic component to position the flow path board at a preset geometric position on a box body.

[0006] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0007] A flow path board positioning device for positioning a flow path board on a synthesizer by compressed air, comprising:

[0008] A box body.

[0009] A positioning component, arranged on the box body, detachably connected to the box body, and located at the top and inside of the box body respectively, for positioning the flow path board on the surface of the box body by means of the driving force of compressed air.

[0010] A pneumatic component is arranged on the box body and connected to the positioning component, and is used to convey compressed air from the box body to the positioning component.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] The pneumatic component conveys compressed air to the positioning component. Under the driving action of the compressed air, the positioning component extends out of the box body and enters the hole of the flow path plate, positioning the flow path plate at the geometric position of the target area on the top of the box body, and then installing the flow path plate, so as to eliminate the situation of difference or reverse installation, and make the flow path plate meet the working requirements.

[0013] Further preferably, the positioning component includes:

[0014] A positioning pin is arranged on the top plate of the box body, sleeved inside the top plate, and movably connected to the top plate.

[0016] A combined pressure strip is arranged on the top plate, located outside the positioning pin, and is detachably connected to the flow path plate, and is used to press the flow path plate tightly on the top plate.

[0017] A fixing member is arranged inside the box body, with a distance from the top plate, and the cylinder is inserted into the fixing member.

[0018] A cover plate is arranged on the bottom surface of the flow path plate, screwed to the flow path plate, and inserted into the positioning pin, and is used to prevent the silicone tube on the flow path plate from falling off.

[0019] Adopting the above technical solution, after the cover plate and the flow path plate are installed together by screwing, the failure of drug synthesis is avoided. The positioning pin extends out of the top plate and enters the cover plate under the driving action of the cylinder, positioning the cover plate on the top plate, and further achieving the purpose of positioning the flow path plate. The combined pressure strip plays a role in fixing the flow path plate, and the cylinder is installed inside the box body through the fixing member.

[0020] Further optimized to be that the number of positioning pins is at least more than 2, and the 2 positioning pins are arranged diagonally on the top plate.

[0021] Adopting the above technical solution, the 2 positioning pins can position the cover plate at the geometric position of the target area in the direction of diagonal wiring, and further achieve positioning the flow path plate at the geometric position. More than 2 positioning pins can achieve the purpose of positioning from multiple directions.

[0022] Further preferably, the fixing member includes:

[0023] A cylinder bottom plate is arranged inside the box body, located below the top plate, and the cylinder is installed in the cylinder bottom plate.

[0024] The back strip is arranged between the cylinder bottom plate and the top plate and is detachably connected to the cylinder bottom plate and the top plate respectively. It is used to connect the cylinder bottom plate to the top plate.

[0025] With the above technical solution, the back strip plays a crucial connecting role between the cylinder bottom plate and the top plate. It can not only install the cylinder inside the box body, but also support the cylinder to push the positioning pin out of the top plate.

[0029] With the above technical solution, the five-way two-position valve delivers the compressed air from the box body to the cylinder, so that the compressed air drives the cylinder to act.

[0030] Further optimized, the upper part of the cylinder is screwed to the positioning pin and is used to push the positioning pin out of the top plate.

[0031] With the above technical solution, the compressed air does work inside the cylinder, drives the cylinder to push the positioning pin out of the top plate, and makes the positioning pin achieve the purpose of bouncing up.

[0032] Further optimized, the inside of the positioning pin is hollow, and a threaded hole is opened inside it. The threaded hole is connected to the upper part of the cylinder.

[0035] With the above technical solution, the compressed air pushes the cylinder away from the cylinder bottom plate, and then pushes the positioning pin to bounce up. When the compressed air is depressurized, the cylinder will fall back on the cylinder bottom plate, and the clamping part contacts the cylinder bottom plate to make the cylinder bottom plate return to its original state.

[0036] Further optimized, the back strip is equal in length to the cylinder bottom plate.

[0037] With the above technical solution, the cylinder bottom plate is completely limited inside the box body. Brief Description of the Drawings

Detailed implementation manners

[0048] The following will further introduce the present utility model in detail with reference to the attached Figures 1 - 9 drawings.

[0049] A flow path plate positioning device, as Figure 1 shown, is used to position the flow path plate 4 on the synthesizer by compressed air, and includes:

[0050] The box body 1, including a front panel 11, a left side panel 12, and a top panel 13, and the top panel 13 is respectively connected to the front panel 11 and the left side panel 12.

[0051] The positioning assembly 2, arranged on the box body 1, is detachably connected to the box body 1, and is respectively located at the top and inside of the box body 1, and is used to position the flow path plate 4 on the surface of the box body 1 by means of the driving force of compressed air.

[0052] The pneumatic assembly 3, arranged on the box body 1, is connected to the positioning assembly 2, and is used to convey the compressed air from the box body to the positioning assembly 2.

[0053] Under the driving action of compressed air, the positioning component 2 extends out of the box body 1 and enters the hole of the flow path plate 4, positioning the flow path plate 4 at the geometric position of the target area on the top of the box body 1, and then installing the flow path plate 4 to eliminate differences or reverse installation situations, so that the flow path plate 4 meets the working requirements. The target area refers to the area on the top plate 13 corresponding to the installation relationship with the flow path plate 4 and presenting the geometric center of the flow path plate 4.

[0054] Specifically, as Figure 1 and Figure 2 shown, in this embodiment, the positioning component 2 includes:

[0055] The positioning pin 21 is arranged on the top plate 13 of the box body 1, sleeved inside the top plate 13, and is movably connected to the top plate 13.

[0056] The air cylinder 20 is arranged inside the box body 1, its upper part is sleeved with the positioning pin 21, and its lower part is connected to the pneumatic component 3.

[0057] The combined pressing strip is arranged on the top plate 13, outside the positioning pin 21, and is detachably connected to the flow path plate 4 for pressing the flow path plate 4 tightly on the top plate 13. The combined pressing strip includes: the upper pressing strip 22, the lower pressing strip 23, the left pressing strip 24 and the right pressing strip 25. The upper pressing strip 22, the left pressing strip 24 and the right pressing strip 25 are connected to the top plate 13 by screws, and the inner wall of the cavity formed by them contacts the outer wall of the flow path plate 4, playing a role in initially limiting the position of the flow path plate 4 on the top plate. The lower pressing strip 23 is detachably connected to the left pressing strip 24 and the right pressing strip 25 respectively. After the flow path plate 4 is positioned by the positioning component 2, the lower pressing strip 23 is connected to the left pressing strip 24 and the right pressing strip 25, and finally positions the flow path plate 4 on the top plate 13.

[0058] The fixing member is arranged inside the box body 1, with a distance from the top plate 13, and the air cylinder 20 is inserted into the fixing member.

[0059] The cover plate 28 is arranged on the bottom surface of the flow path plate 4, is screwed to the flow path plate 4, and is inserted into the positioning pin 21 for preventing the silicone tube on the flow path plate 4 from falling off. During the synthesis process of radioactive drugs, a plurality of silicone tubes are installed on the flow path plate 4. The cover plate 28 can prevent the silicone tubes from falling off the flow path plate 4, and even prevent disconnection between two connected silicone tubes, effectively avoiding the failure of radioactive drug synthesis. Among them, the installation of the silicone tubes on the flow path plate 4 is prior art, so it is not shown in the figure and will not be elaborated.

[0060] After the cover plate 28 and the flow path plate 4 are installed together by screwing, the positioning pin 21 extends out of the top plate 13 and enters the cover plate 28 under the driving action of the air cylinder 20, positioning the cover plate 28 on the top plate 13, and further achieving the purpose of positioning the flow path plate 4. The combined pressing strip plays a role of fixing the flow path plate 4 twice, and the air cylinder 20 is installed inside the box body 1 through the fixing member.

[0061] Specifically, as Figure 1 、 Figure 2 and Figure 3 shown, the number of the positioning pins 21 is at least two or more, and the two positioning pins 21 are arranged diagonally on the top plate 13. The two positioning pins 21 can position the cover plate 28 at the geometric position of the target area in the direction of the diagonal row, and further position the flow path plate 4 at the geometric position. Two or more positioning pins 21 can play a positioning role from multiple directions.

[0062] Specifically, as Figure 1 and Figure 3 shown, the fixing member includes:

[0063] The cylinder bottom plate 26 is arranged inside the box body 1 and below the top plate 13, and the cylinder 20 is installed in the cylinder bottom plate 26.

[0064] The back strip 27 is square and is arranged between the cylinder bottom plate 26 and the top plate 13, on one side of the cylinder 20, and is detachably connected to the cylinder bottom plate 26 and the top plate 13 respectively. It is used to connect the cylinder bottom plate 26 to the top plate 13.

[0065] The back strip 27 plays a crucial connecting role between the cylinder bottom plate 26 and the top plate 13. It can not only install the cylinder 20 inside the box body 1, but also support the cylinder 20 to push the positioning pin 21 out of the top plate 13.

[0066] Specifically, as Figure 1 and Figure 3 shown, the pneumatic component 3 in this embodiment includes:

[0067] The lighted switch 31 is arranged on the front panel 11 of the box body 1 and is detachably connected to the front panel 11. It is connected to an external power supply. This is the prior art and will not be elaborated here.

[0068] The five-way two-position valve 32 is arranged inside the box body 1. Its electrical end is connected to the lighted switch 31, and its air source end is connected to the cylinder 20. It is used to deliver compressed air to the cylinder 20.

[0069] The five-way two-position valve 32 delivers the compressed air from the lighted switch 31 into the cylinder 20, so that the compressed air drives the cylinder 20 to act.

[0070] Specifically, as Figure 4 、 Figure 7 and Figure 8 shown, the upper part of the cylinder 20 in this embodiment is screwed to the positioning pin 21 and is used to push the positioning pin 21 out of the top plate 13. The compressed air does work inside the inner cylinder 20, driving the cylinder 20 to push the positioning pin 21 out of the top plate 13, so that the positioning pin 21 reaches the purpose of bouncing up.

[0071] Specifically, as Figure 9 shown, the positioning pin 21 in this embodiment is hollow inside, and a threaded hole 211 is provided inside it. The threaded hole 211 is connected to the upper part of the air cylinder 20. After the positioning pin 21 and the air cylinder 20 are connected together, the air cylinder 20 is used to push the positioning pin 21 to produce a bouncing action.

[0072] Specifically, as Figure 8 shown, a clamping member 201 is provided on the outer wall of the air cylinder 20 in this embodiment. The clamping member 201 contacts the air cylinder bottom plate 26. Compressed air pushes the air cylinder 20 away from the air cylinder bottom plate 26, and then pushes the positioning pin 21 to bounce. When the compressed air is depressurized, the air cylinder 20 will fall back onto the air cylinder bottom plate 26, and the clamping member 201 contacts the air cylinder bottom plate 26 to restore the air cylinder bottom plate 26 to its original state.

[0073] Specifically, as Figure 4 , Figure 5 and Figure 6 shown, the back strip 27 in this embodiment is equal in length to the air cylinder bottom plate 26, and completely confines the air cylinder bottom plate 26 inside the box body 1.

[0074] Please refer to Figures 1 - 9 , and the working principle and process of this embodiment are described as follows:

[0075] First, connect the flow path plate 4 and the cover plate 28 together with screws, and then place them in the target area of the top plate 13, so that the three outer walls of the flow path plate 4 are respectively in pressing contact with the upper pressing strip 22, the left pressing strip 24, and the right pressing strip 25, which plays a primary rough positioning role for the flow path plate 4. Press the start button with a light to make the five-way two-position valve 32 energized and opened, and simultaneously send the compressed air from the box body 1 to the two air cylinders 20. The two air cylinders 20 push the positioning pins 21 to pop out of the top plate 13 under the action of the compressed air. At the same time, the positioning pins 21 extend into the cover plate 28 to position the cover plate 28 at the geometric position of the target area. Since the flow path plate 4 and the cover plate 28 are connected together, the flow path plate 4 is also positioned at this geometric position to achieve secondary positioning. Tighten the two ends of the lower pressing strip 23 to the left pressing strip 24 and the right pressing strip 25 with screws respectively to fix the flow path plate 4 together, and finally accurately position the flow path plate 4 at the geometric position of the target area.

[0076] In summary, the pneumatic component 3 provides power to the positioning component 2, and the positioning component 2 accurately positions the flow path plate 4 on the top plate 13 in the way of popping out the top plate 13 for positioning, which can eliminate the differences existing during the installation of the flow path plate 4 and make it meet the working requirements.

[0077] This specific embodiment is only an interpretation of the utility model and does not limit the utility model. After reading this specification, those skilled in the art may make modifications to this embodiment that do not contribute creatively as needed, but as long as they are within the protection scope of the utility model, they are protected by the Patent Law.
