DETAILED DESCRIPTION

[0033] The following is the specific embodiment of the utility model and is combined with the drawings, and the technical scheme of the utility model is further described, but the utility model is not limited to these embodiments.

[0034] As Figures 1 to 6 The utility model discloses a cutting mechanism, including: plane moving module 110 and sliding module 120, cutting element 200, cutting element 200 installs in plane moving module 110, cutting platform 300 is set up as the structure that can produce adsorption force, cutting platform 300 installs in sliding module 120, and the stroke position of cutting platform 300 includes cutting station and placement station, and cutting station and cutting element 200 movable region are set up as being located at opposite sides respectively, when cutting platform 300 is located in cutting station, cutting platform 300 is located at the opposite side of cutting element 200.

[0035] Plane moving module 110 is mainly used for driving cutting element 200 to move in a plane (horizontal plane or vertical plane) to make cutting element 200 cut out the filter paper piece of same shape according to the shape of lesion, and plane moving module 110 is preferably CoreXY module. Sliding module 120 is mainly used for driving cutting platform 300 to move linearly, so that cutting platform 300 is driven to cutting station or placement station, and sliding module 120 is preferably air cylinder or linear motor or screw motor or sliding table or linear driver.

[0036] In addition to sucking filter paper piece in the cutting process, cutting platform 300 can also realize the function of grabbing and transferring. Cutting platform 300 can generate the suction force of sucking filter paper piece, which means that it can firmly adsorb filter paper in the cutting process and the transfer process, prevent filter paper from any displacement, and ensure that cutting platform 300 can drive filter paper piece to transfer. Cutting element 200 can cut filter paper, and plane moving module 110 drives cutting element 200 to move according to the set trajectory, so as to cut out the filter paper piece of set shape on the filter paper belt, which is used for subsequent transfer to titration platform 500 (lower film) to add phosphorus-32. The movable region of cutting element 200 refers to the two-dimensional plane region that cutting element 200 can move and operate when performing the cutting task.

[0037] The cutting platform 300 is located opposite the cutting element 200 at the cutting station. This design allows the cutting element 200 to cut the filter paper from the opposite side of the cutting platform 300. Since the cutting platform 300 holds the filter paper, after the cutting platform 300 moves the filter paper to the placement station, it can transfer the filter paper to the adhesive surface of the lower film on the titration platform 500. This greatly simplifies the operation steps and eliminates the need for repeated positioning and additional gripping mechanisms, ensuring the smoothness and reliability of the entire automated preparation process.

[0038] like Figures 1 to 3 , Figure 6 As shown, based on the above embodiment, the sliding module 120 is equipped with a telescopic drive element 400, and the cutting platform 300 is connected to the sliding module 120 through the telescopic drive element 400. The sliding module 120 can drive the cutting platform 300 to slide through the telescopic drive element 400, and the telescopic drive element 400 can drive the cutting platform 300 to extend and retract.

[0039] The telescopic drive element 400 can be a cylinder or solenoid valve, or similar component capable of short-range actuation. The telescopic drive element 400 is used to move the cutting platform 300 closer to or further away from the opposite side. When the cutting platform 300 is at the cutting station, it maintains a certain distance from the filter paper strip; that is, the cutting platform 300 and the filter paper strip do not directly contact each other. During cutting, the telescopic drive element 400 drives the cutting platform 300 to extend a certain distance, causing the cutting platform 300 to contact and hold the filter paper strip. Then, the cutting element 200 cuts the filter paper strip above. After cutting, the telescopic drive element 400 drives the cutting platform 300 to retract. At this point, the filter paper sheet held by the cutting platform 300 separates from the filter paper strip. In subsequent steps, the cutting platform 300 can directly transfer the filter paper sheet to the placement station without needing to reposition and grip the filter paper sheet, reducing a large number of intermediate structures (e.g., eliminating the need for a dedicated gripping mechanism) and corresponding operating steps.

[0040] Example 1:

[0041] like Figures 1 to 7 As shown, the cutting platform 300 includes a platform base 310 and a negative pressure generator. The platform base 310 is connected to the sliding module 120. The negative pressure generator is installed on the platform base 310. The platform base 310 has adsorption holes 320 on its adsorption surface. When the negative pressure generator is running, it generates suction force on the adsorption surface of the platform base 310 through the adsorption holes 320.

[0042] The platform base 310 is the main support structure of the cutting platform 300, and is connected with the sliding module 120 and can move to the cutting station and the placing station. The negative pressure generator is located in the platform base 310, and is responsible for generating negative pressure. The suction holes 320 are used to generate suction force on the suction surface of the platform base 310 to suck the filter paper. This design can greatly improve the anti-interference ability during cutting and transferring. The negative pressure suction force can firmly adsorb the filter paper sheet, avoid position deviation caused by loosening or sliding during transferring, ensure the accurate position of the filter paper sheet after cutting, facilitate subsequent transferring and processing, and improve the accuracy of the entire preparation process. In addition, through negative pressure adsorption, the filter paper sheet can be firmly fixed on the platform base 310. When the platform base 310 is stretched or contracted, the filter paper sheet can be smoothly separated from the filter paper strip under the action of negative pressure suction. When the platform base 310 needs to place the filter paper sheet, the negative pressure generator can be turned off, and the filter paper sheet can be separated from the suction surface of the platform base 310.

[0043] On the basis of the first embodiment, a movable top plate 311 is arranged in the platform base 310. The top plate 311 is provided with a plurality of top rods 312. Each top rod 312 is aligned with each suction hole 320. The top plate 311 can be moved to an ejection position. When the top plate 311 is in the ejection position, each top rod 312 is ejected from each suction hole 320.

[0044] The top plate 311 can eject the sucked filter paper sheet through the top rod 312. When the negative pressure generator generates negative pressure in the platform base 310, the negative pressure in the platform base 310 sucks the filter paper sheet through the plurality of suction holes 320. When the platform base 310 moves to the opposite side of the titration platform 500, the filter paper sheet needs to be separated from the suction surface of the platform base 310, so as to achieve the purpose of transferring the filter paper sheet.

[0045] In order to better achieve this purpose, the top plate 311 is specially arranged in the platform base 310. The top plate 311 can approach or move away from the suction surface of the platform base 310. When the top plate 311 approaches the suction surface of the platform base 310, the top rod 312 is extended from the suction hole 320, so as to eject the filter paper sheet on the suction surface, ensure that the filter paper sheet is separated from the suction surface of the platform base 310, and then transferred to the titration platform 500 (on the adhesive surface of the lower film). When the top plate 311 moves away from the suction surface of the platform base 310, the top rod 312 is withdrawn from the suction hole 320, so that the platform base 310 can adsorb the filter paper sheet.

[0046] Embodiment II:

[0047] The cutting platform 300 comprises a platform base 310 and an electrostatic generator. The platform base 310 is connected with the sliding module 120. The electrostatic generator is installed on the platform base 310. When the electrostatic generator operates, the suction surface of the platform base 310 generates an electrostatic field.

[0048] When the high voltage generated by the electrostatic generator is transmitted to the platform base 310 through the electrode, the adsorption surface of the platform base 310 will be charged with static electricity. When the filter paper sheet approaches the adsorption surface of the platform base 310, the surface of the filter paper sheet will be charged with opposite charges due to electrostatic induction, thereby being attracted by the electrostatic field. Therefore, the electrostatic field can tightly adsorb the filter paper sheet on the bottom surface of the platform base 310, preventing the material from moving during cutting and ensuring cutting accuracy and stability. When the platform base 310 needs to release the filter paper sheet, the electrostatic generator can be turned off, and the filter paper sheet can be separated from the adsorption surface of the platform base 310.

[0049] As shown in Figures 1 to 3 , Figure 5 , on the basis of the above embodiments, the cutting element 200 is provided as a laser cutter or an ultrasonic cutter or a hob or a drag knife.

[0050] The cutting element 200 can be cut by laser cutting or mechanical cutting. In the example, the cutting element 200 is preferably a laser cutter.

[0051] When the cutting element 200 adopts a mechanical cutting method, the cutting element 200 can be provided as an ultrasonic cutter or a hob or a drag knife. Among them, the ultrasonic cutter is a cutter that uses ultrasonic energy for cutting, the hob is a cutting tool with rotating blades, and the basic principle of the hob is to drive the blades to rotate at high speed by the motor, and to realize the cutting of the material by using the centrifugal force and the sharpness of the blade. The working method of the drag knife is to apply a certain pressure on the surface of the material by the machine arm, and to move along the predetermined path, and to complete the cutting by using the sharpness of the knife tip. In short, the cutting element 200 can select any element that can cut the filter paper sheet.

[0052] As shown in Figures 1 to 6 , on the basis of the above embodiments, when the cutting platform 300 is located at the cutting station, one of the cutting platform 300 and the cutting element 200 is arranged in correspondence with the other in an up-down manner or in a front-rear manner or in a left-right manner. Through the above arrangement, the cutting platform 300 and the cutting element 200 can be located on opposite sides (i.e. upper side and lower side or left side and right side or front side and rear side) respectively.

[0053] As shown in Figures 2 to 5 , on the basis of the above embodiments, two groups of conveying roller groups 130 are further included, and the two groups of conveying roller groups 130 are respectively located on the two sides of the cutting station, and a filter paper path is formed between the two groups of conveying roller groups 130, and the filter paper path is located between the cutting station and the active area of the cutting element 200.

[0054] This embodiment can automatically guide the filter paper between the cutting station and the active area of ​​the cutting element 200, ensuring that the filter paper can be smoothly and accurately conveyed between the cutting station and the active area of ​​the cutting element 200. The conveying roller group 130 consists of two parallel rollers. The conveying roller group 130 located behind the filter paper conveying path is set as an active drive structure. Through the two conveying roller groups 130, the filter paper belt can be continuously driven through the area between the cutting station and the active area of ​​the cutting element 200, which facilitates the cutting element 200 to continuously cut filter paper sheets, thereby realizing the function of continuously and automatically preparing the radionuclide applicator.

[0055] Taking the cutting station located above the cutting element 200 as an example, the filter paper strip between the two conveying roller groups 130 is located between the cutting station and the active area of ​​the cutting element 200. The cutting platform 300 is located at the cutting station and descends to hold this part of the filter paper strip. The cutting element 200 cuts the filter paper above. After the cutting is completed, the cutting platform 300 rises and takes the cut filter paper pieces off the filter paper strip. At this time, there is a notch on this part of the filter paper strip. Then the conveying roller group 130 drives the filter paper strip to move forward, bringing the next section of the filter paper strip to the area between the cutting station and the active area of ​​the cutting element 200, so as to facilitate the next cutting of the filter paper.

[0056] Based on the above embodiments, the system also includes a frame 100, a planar moving module 110, a sliding module 120, and two sets of conveying roller groups 130, all of which are fixed to the frame 100.

[0057] like Figures 1 to 7 As shown, based on the above embodiments, a radionuclide applicator preparation device includes a cutting mechanism and a titration platform 500. The titration platform 500 and the placement station are respectively located on opposite sides. When the cutting platform 300 is located at the placement station, the cutting platform 300 is located opposite the titration platform 500.

[0058] This radionuclide applicator preparation equipment is a fully automated system. Therefore, accurate coordination is required during the cutting, transfer, and titration steps to ensure the automatic preparation of the radionuclide applicator. If the equipment cannot accurately transfer the filter paper onto the titration platform 500 after cutting, the preparation will fail and affect subsequent preparations.

[0059] For example, when the cutting station is above the cutting element 200, the two sets of conveying rollers 130 convey the filter paper strip according to the preparation rhythm, then the cutting platform 300 at the cutting station is lowered and then sucks the filter paper strip, the planar moving module 110 drives the cutting element 200 to cut the filter paper above (the laser cutter emits laser upward to cut the filter paper), after cutting, the cutting platform 300 is raised to separate the filter paper piece, then the sliding module 120 drives the cutting platform 300 to move to the titration station, the cutting platform 300 removes the suction force and the top plate 310 starts to move, the top rod 320 on the top plate 310 passes through the suction hole 320 to eject the filter paper piece, the filter paper piece is pasted on the adhesive surface of the lower film on the titration platform 500, then the titration device starts to work to accurately drop the phosphorus-32 drug on the filter paper piece, thereby realizing accurate connection of the cutting, transferring and titration steps, achieving the purpose of automatic preparation of the nuclide applicator, and greatly enhancing the smoothness of the automatic preparation process, reducing a large number of intermediate structures (for example, a special grabbing mechanism is omitted) and corresponding operation steps.

[0060] It should be noted here that the titration platform 500 is located on the same side as the cutting element 200, if the cutting station and the cutting element 200 are respectively located on the left and right sides or the front and back sides or the cutting station is located below the cutting element 200, the filter paper piece cannot fall on the titration platform 500 under the action of gravity. When the filter paper piece needs to be transferred to the titration platform 500 in this layout, the telescopic driving element 400 drives the cutting platform 300 to extend towards the titration platform 500, so that the filter paper piece is pasted on the adhesive surface of the lower film on the titration platform 500, and then the cutting platform 300 removes the negative pressure suction force, thereby realizing the transfer of the filter paper piece.

[0061] On the basis of the above embodiment, a filter paper supply module 140 for supplying filter paper is further included, the filter paper is arranged to pass through the two sets of conveying rollers 130 in sequence, thereby being located between the cutting station and the active area of the cutting element 200. The filter paper supply module 140 can continuously provide filter paper, ensuring uninterrupted preparation process.

[0062] On the basis of the above embodiment, a lower film supply module 150 for supplying lower film is further included, the moving path of the lower film is arranged to pass through the surface of the titration platform 500, and the moving path of the lower film is located opposite the placement station.

[0063] The lower film supply module 150 can continuously provide the lower film for the titration platform 500, the lower film passes through the upper surface of the titration platform 500, thereby being placed below the placement station, the adhesive surface of the lower film faces upward, when the cutting platform 300 places the filter paper piece on the lower film, the lower film can stick the filter paper piece through the adhesive surface, then the titration device drops the phosphorus-32, and finally the upper film is pasted on the lower film to seal the filter paper piece.

[0064] It should be noted that all directional indications, such as upper, lower, left, right, front, rear, etc., in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.
