Description

Technical Field

[0001] This invention relates to the field of electrodeposition equipment technology, and in particular to a radiation source-assisted electrodeposition pressure frame and device. Background Technology

[0002] Beta radiation sources have a short range, and due to self-absorption and absorption by the support, beta particles cannot reach the detector, thus affecting detection efficiency. Therefore, beta radiation sources are generally fabricated using methods such as electroplating or microporous adsorption with aluminum oxide layers. Electroplating involves electroplating metal ions containing beta particle emitters onto the electrode surface based on the electrode potential of the metal ions in the beta particle emitter.

[0003] In the prior art, the electrodeposition tank for preparing a 170mm×120mm radioactive source is a rectangular tank divided into upper and lower parts. The upper part has a rectangular groove with a sealing rubber ring inside. Then, a metal substrate is placed on top, and finally, the lower part of the tank is placed on the metal substrate. After aligning the upper and lower tanks with screw holes, they are fastened with screws.

[0004] Actual research revealed that the electrodeposition tanks with the above-mentioned structure have some insurmountable defects in practical use: 1) When fixing the tank, at least 12 screws need to be tightened one by one using specific tools. When disassembling, they also need to be loosened one by one. This operation is time-consuming and laborious, especially in small-batch, multi-batch preparation scenarios, which seriously restricts production efficiency.

[0005] 2) Uneven force may occur during screw tightening, with some screws being too tight and others too loose, causing abnormal local pressure on the sealing rubber ring, resulting in seal failure, which in turn leads to electrolyte leakage or air infiltration, affecting the electrodeposition effect.

[0006] 3) Screws are prone to stripping and thread damage after frequent disassembly and assembly, which not only affects the service life and reliability of the equipment, but also further increases the risk of electrolyte leakage.

[0007] 4) When disassembling and assembling screws, workers need to bend over frequently, which may pose a risk of contact if there is residual electrolyte in the tank.

[0008] In light of the aforementioned problems and findings, how to further improve operational efficiency and ensure the safety and reliability of equipment has become a critical technical challenge that urgently needs to be addressed.

[0009] It should be clarified here that the above description is intended to facilitate understanding of the overall background of the present invention, and should not be construed as an admission or implication in any way that the information constitutes prior art known to those skilled in the art.

[0020] According to the present invention, a radiation source-assisted electrodeposition pressure frame is provided, wherein a connecting block is fixedly connected to the sliding member, and the transmission arm is hinged to the connecting block.

[0021] The present invention also provides a radioactive source-assisted electrodeposition apparatus, comprising a radioactive source-assisted electrodeposition pressure frame as described in any one of the above claims, and an electrodeposition tank supported on the source frame; The pressing end of the pressure mechanism moves closer to or further away from the support surface to press or release the electrodeposition tank.

Furthermore, it eliminates the need for operators to frequently bend over to install and remove screws, reducing the risk of close contact with the electrodeposition tank and electrolyte, thus improving operational safety. In addition, replacing the traditional multi-screw fastening method with a pressing and sealing method avoids uneven force distribution during multi-screw fastening, thereby reducing the risk of electrolyte leakage. It also avoids problems such as stripped threads and thread damage caused by frequent screw installation and removal during long-term use, further reducing the risk of electrolyte leakage, improving the reliability and safety of the device, and lowering maintenance costs.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0032] To better understand the radiation source-assisted electrodeposition pressure stand and apparatus provided in the embodiments of the present invention, its application background is first introduced. In the prior art, the electrodeposition tank used to prepare radiation sources is a rectangular tank, which is divided into upper and lower parts. The upper part has a rectangular groove with a sealing rubber ring in the groove. Then, a metal substrate is placed on it, and finally, the lower part of the tank is placed on the metal substrate. After the upper and lower tanks are aligned with the screw holes, they are tightened by screws.

[0033] Actual research revealed that the electrodeposition tank with the aforementioned structure requires the use of specific tools to tighten at least 12 screws individually during fixing and loosening them individually during disassembly. This operation is time-consuming and labor-intensive, especially in small-batch, multi-batch preparation scenarios, severely restricting production efficiency. Furthermore, workers need to frequently bend over during screw installation and removal, posing a risk of contact if residual electrolyte remains in the tank. In addition, uneven force can easily occur during screw tightening, with some screws being too tight and others too loose, leading to abnormal local pressure on the sealing rubber ring, sealing failure, and subsequent electrolyte leakage or air infiltration, affecting the electrodeposition effect. At the same time, frequent disassembly and reassembly of the screws can easily cause problems such as stripped threads and thread damage, which not only affects the service life and reliability of the equipment but also further increases the risk of electrolyte leakage.

[0034] In view of the above problems and findings, embodiments of the present invention provide a radiation source-assisted electrodeposition pressure frame and device, which replaces the traditional connection method of multiple screw fastening, is simple and convenient to operate, helps to further improve work efficiency, and has high sealing reliability and safety.

[0035] The following is combined Figures 1 to 5 The present invention describes a radiation source-assisted electrodeposition pressure frame and apparatus.

[0036] Reference Figure 1 and Figure 2 A radiation source-assisted electrodeposition pressure frame includes a frame 11, a pressure mechanism 12, a transmission mechanism 13, and a drive mechanism 14. The frame 11 has a source stage 110 with a support surface for supporting a radiation source sheet. The pressure mechanism 12 is connected to the frame 11 and has a pressing end 120 facing the support surface. The pressure mechanism 12 is slidably connected to the frame 11, and the pressing end 120 can move closer to or away from the support surface as the pressure mechanism 12 slides. The pressure mechanism 12 is connected to the drive mechanism 14 via the transmission mechanism 13, which converts the driving force of the drive mechanism 14 into the sliding force of the pressure mechanism 12, causing the pressing end 120 to move closer to or away from the support surface.

[0037] In practical applications, during electrodeposition, the radioactive source sheet and electrodeposition tank 20 are placed on the support surface of the source stage 110. Then, the pressure mechanism 12 is driven to slide by the drive mechanism 14 and the transmission mechanism 13. The pressing end 120 of the pressure mechanism 12 moves close to the support surface of the source stage 110 to press the electrodeposition tank 20, thereby conveniently and quickly achieving the pressing and sealing of the electrodeposition tank 20. After sealing, the DC power supply is connected (cathode connected to the negative terminal of the power supply, anode connected to the positive terminal of the power supply) to carry out the electrodeposition reaction. After the electrodeposition reaction is completed, the pressure mechanism 12 is driven to slide by the drive mechanism 14 and the transmission mechanism 13, so that the pressing end 120 of the pressure mechanism 12 moves away from the support surface of the source stage 110 to release the electrodeposition tank 20, thereby achieving convenient and quick disassembly of the electrodeposition tank 20.

[0038] Compared to related technologies, this pressure frame, through the cooperation of the drive mechanism 14 and the transmission mechanism 13, drives the pressing end 120 of the pressure mechanism 12 to move closer to or away from the support surface of the source platform 110. This facilitates and quickly achieves the pressing, sealing, fixing, loosening, and disassembly of the electrodeposition reaction tank, eliminating the need for operators to use specific tools to tighten or loosen multiple screws one by one. The operation process is simple and convenient, shortening the operation time of a single operation, reducing labor intensity, and effectively improving the operation efficiency in small-batch, multi-batch preparation scenarios. Furthermore, operators do not need to frequently bend over to install or remove screws, reducing the risk of close contact with the electrodeposition tank 20 and electrolyte, thus improving operational safety. In addition, replacing the traditional connection method of multiple screws with a pressing and sealing method avoids the problem of uneven force during the tightening of multiple screws, thereby reducing the risk of electrolyte leakage. At the same time, it also avoids problems such as stripping and thread damage caused by frequent screw installation and removal during long-term use, which helps to further reduce the risk of electrolyte leakage, improve the reliability and safety of the device, and reduce maintenance costs.

[0039] Understandably, the frame 11 serves as the supporting foundation for the entire device, providing connection points for various components. The specific materials, structural forms, dimensions, and other parameters of the frame 11 can be selected and designed according to the actual application scenario.

[0040] In one example of the present invention, the frame 11 includes a base 111 and a connecting frame 112; wherein, the upper and lower surfaces of the base 111 are both set as planes, and the source platform 110 is disposed on the upper surface of the base 111, which is configured as a platform structure protruding from the upper surface of the base 111; the source platform 110 and the base 111 can be connected in a detachable manner, such as by connecting components such as bolts, or in a non-detachable manner, such as by welding or integral molding, depending on the actual application scenario, and no specific limitation is made here. The specific shape and size specifications of the source platform 110 need to be designed according to the electrodeposition tank 20. In this embodiment, the electrodeposition tank 20 is a rectangular tank, and correspondingly, the source platform 110 is configured as a rectangular platform protruding from the upper surface of the base 111.

[0041] In one example of the present invention, the connecting frame 112 is configured as a portal frame and fixedly connected to the upper surface of the base 111, and the pressure mechanism 12, the transmission mechanism 13 and the drive mechanism 14 are all disposed on the connecting frame 112.

[0042] The specific structure of the pressure mechanism 12 will be described below with reference to the accompanying drawings.

[0043] In one example of the present invention, the pressing end 120 of the pressure mechanism 12 is configured as an elastic pressing end 120 to provide an elastic preload force toward the support surface. With this configuration, compared to the localized misfitting that can easily occur with rigid pressing, the elastic pressing end 120 can adaptively compensate for minute dimensional differences in the upper surface of the electrodeposition tank 20 through its own elastic preload force, allowing the elastic preload force to be transmitted to the entire upper surface of the electrodeposition tank 20. This effectively improves sealing reliability and reduces impurity interference during the electroplating process. Furthermore, the elastic pressing end 120 can also absorb instantaneous stress during pressure transmission through elastic deformation, effectively buffering instantaneous impacts, reducing the risk of damage to the electrodeposition tank 20 and other workpieces, and extending the service life of the entire support and the electrodeposition tank 20.

[0044] To elaborate further, refer to Figures 1 to 3 The pressure mechanism 12 includes a base 121, a pressure block 122, and an elastic element 123. The base 121 is slidably connected to the frame 11 and can move closer to or further away from the support surface. The pressure block 122 is slidably connected to the base 121, and one end of the pressure block 122 away from the base 121 in the sliding direction is formed as a pressing end 120. The elastic element 123 is connected between the base 121 and the pressure block 122 and is used to provide a preload force for the pressure block 122 to slide closer to the support surface.

[0045] With this configuration, the sliding connection between the pressure block 122 and the substrate 121 forms a retractable buffer stroke. When the drive mechanism 14 moves the substrate 121 closer to the support surface, the pressure block 122 first contacts the upper surface of the electrodeposition tank 20. As the substrate 121 continues to move downward, the elastic element 123 is compressed and generates a gradually increasing preload, thereby pressing and sealing the electrodeposition tank 20. When the drive mechanism 14 moves the substrate 121 away from the support surface, the pressure block 122 gradually releases the electrodeposition tank 20, and the elastic element 123 returns to its original shape.

[0046] In detail, a pressure chamber 124 is provided at one end of the base 121 facing the support surface. A guide hole is provided at one end of the pressure chamber 124 facing the support surface. A pressure block 122 is slidably inserted through the guide hole to form a limiting end 125 located inside the pressure chamber 124 and the aforementioned pressing end 120 located outside the pressure chamber 124. The outer diameter of the limiting end 125 and the pressing end 120 is larger than the diameter of the guide hole.

[0047] With this configuration, the pressure chamber 124 can provide sliding space for the pressure block 122. The limiting end 125 and the pressing end 120, whose outer diameter is larger than that of the guide hole, can restrict the pressure block 122 on the pressure chamber 124, preventing the pressure block 122 from detaching from the base 121 and limiting the sliding stroke of the pressure block 122. The guide hole can constrain the sliding direction of the pressure block 122, ensuring the stability and smoothness of the sliding of the pressure block 122.

[0048] In detail, the elastic element 123 is configured as a spring, which is sleeved on the pressure block 122, and the two ends of the spring elastically abut against the pressing end 120 and the pressure chamber 124, respectively. With this configuration, when the drive mechanism 14 drives the pressure block 122 to contact the upper surface of the electrodeposition tank 20, as the substrate 121 continues to move downward, the spring is compressed and generates a gradually increasing preload, pressing and sealing the electrodeposition tank 20; when the drive mechanism 14 drives the substrate 121 away from the support surface, the pressure block 122 gradually releases the electrodeposition tank 20, and the spring returns to its original deformation.

[0049] In order to make the contact surface between the pressure mechanism 12 and the electrodeposition tank 20 more uniformly stressed, in one example of the present invention, multiple pressure blocks 122 are provided, and the shape of the multiple pressure blocks 122 is adapted to the shape of the upper end surface of the electrodeposition tank 20.

[0050] In detail, taking a rectangular electrodeposition tank 20 as an example, multiple pressure blocks 122 arranged along the length of the electrodeposition tank 20 are arranged in one row, and two rows of pressure blocks 122 are spaced apart along the width of the electrodeposition tank 20. This arrangement allows the two rows of pressure blocks 122 to apply pressure simultaneously at multiple points on both sides of the electrodeposition tank 20, improving the uniformity of pressure distribution and effectively preventing electrolyte leakage due to insufficient local pressure, or deformation of the electrodeposition tank 20 or its rubber ring due to excessive local pressure.

[0051] Of course, the above is just an example. When the electrodeposition tank 20 is of other shapes, the arrangement of the pressure blocks 122 can also be adjusted accordingly, which will not be listed one by one here.

[0052] The specific structure of the transmission mechanism 13 will be described below with reference to the accompanying drawings.

[0053] In one example of the present invention, the pressure mechanism 12 is slidably connected to the frame 11 via a sliding member 15.

[0054] In detail, the sliding member 15 is configured as a rod-shaped structure and arranged along the movement direction of the pressure mechanism 12; the frame 11 is provided with a sliding hole, and the sliding member 15 is slidably inserted into the sliding hole, with the pressure mechanism 12 fixedly connected to the sliding member 15. This arrangement, with the cooperating rod-shaped sliding member 15 and the sliding hole, constrains the sliding direction of the pressure mechanism 12, ensuring it can only move along a preset trajectory, thus preventing lateral deviation or swaying of the pressure mechanism 12 during lifting and lowering.

[0055] In one example of the present invention, the transmission mechanism 13 includes a first link 130, a second link 131, and a third link 132; wherein, one end of the first link 130 is close to the sliding member 15 and hinged to the frame 11 at a first hinge point 134, the rotation axis of the first link 130 is perpendicular to the movement direction of the pressure mechanism 12, and the drive mechanism 14 is used to drive the first link 130 to swing; one end of the second link 131 is hinged to the first link 130 at a second hinge point 135, and the other end faces the source platform 11. Extending in the 0 direction; one end of the third link 132 is hinged to the end of the second link 131 away from the first link 130 at the third hinge point 136, and the other end is hinged to the frame 11 at the fourth hinge point 137, with the fourth hinge point 137 being closer to the sliding member 15 relative to the third hinge point 136; one end of the transmission arm 133 is hinged to the third link 132 at the fifth hinge point 138, and the other end is hinged to the sliding member 15 at the sixth hinge point 139, with the fifth hinge point 138 located between the third hinge point 136 and the fourth hinge point 137.

[0056] With this configuration, the first link 130, the second link 131, the third link 132, and the frame 11 form a structure similar to a four-bar linkage. When the drive mechanism 14 drives the first link 130 to swing upward, it simultaneously causes the fifth hinge point 138 of the second link 131, the third link 132, and the transmission arm 133 to swing upward and close to the sliding member 15. Simultaneously, the fifth hinge point 138 swings, causing the sixth hinge point 139 to move downward. The sliding member 15 slides downward under the influence of the sixth hinge point 139, thereby causing the pressure mechanism 12 to move downward to press and seal the electrodeposition tank 20. When the first link 130 swings to a vertical position, the electrodeposition tank 20... The reaction force applied by the sedimentation tank 20 to the pressure mechanism 12 coincides with the axis of the first connecting rod 130, making it impossible to push the first connecting rod 130 to swing, thus forming a structural dead point to achieve self-locking and keeping the pressure mechanism 12 in a pressed state. When the drive mechanism 14 drives the first connecting rod 130 to swing downward, it drives the second connecting rod 131, the third connecting rod 132, and the fifth hinge point 138 of the transmission arm 133 to swing downward and away from the sliding member 15 at the same time. While the fifth hinge point 138 swings, it drives the sixth hinge point 139 to move upward. The sliding member 15 slides upward under the drive of the sixth hinge point 139, and the pressure mechanism 12 moves away from the support surface and releases the pressed state.

[0057] In detail, the first link 130, the second link 131, and the third link 132 are each arranged in pairs. This arrangement effectively increases the load-bearing cross-section of each link, thereby improving the structural rigidity of each link and ensuring the stability and reliability of the transmission.

[0058] Furthermore, the transmission arm 133 is configured as an arc-shaped arm protruding towards the first connecting rod 130. This configuration allows the arc-shaped arm to better match the motion trajectories of the fifth hinge point 138 and the sixth hinge point 139, optimizing the force transmission path. Compared to a straight arm, the curved surface structure of the arc-shaped arm can evenly distribute stress throughout the entire arm body, reducing stress peaks at the hinge points. Simultaneously, the bending stiffness of the arc-shaped structure is superior to that of a straight arm of the same specifications, effectively reducing the risk of deformation and ensuring the stability and service life of the transmission mechanism 13.

[0059] Furthermore, a connecting block 151 is fixedly connected to the sliding member 15, and the transmission arm 133 is hinged to the connecting block 151 to achieve connection with the sliding member 15. This arrangement avoids the load applied by the transmission arm 133 from directly acting on the sliding member 15, reducing wear and deformation of the sliding member 15, ensuring the stability and smoothness of the sliding of the sliding member 15, and improving the service life of the sliding member 15.

[0060] Furthermore, the connecting block 151 and the sliding member 15 can be detachably connected via bolts or other connecting components. This allows for easy replacement of faulty components by simply disassembling the connecting block 151 when the transmission arm 133 or the hinge shaft becomes worn or damaged, without needing to disassemble the sliding member 15, thus reducing maintenance costs. Alternatively, the connecting block 151 and the sliding member 15 can be connected in a non-detachable manner (e.g., by welding or integral molding) to ensure the stability and load-bearing capacity of the overall structure. The choice and design of either of these connection methods between the connecting block 151 and the sliding member 15 should be based on actual requirements, and no specific limitations are imposed here.

[0061] In one example of the present invention, the drive mechanism 14 is configured as an operating handle fixedly connected to the first link 130. With this configuration, the operator can drive the first link 130 to swing by pulling the handle, thereby completing the "pressing-locking-unlocking" process of the pressure mechanism 12. The entire operation requires no complex electrical control or pneumatic adjustment and can be completed by a single person. This is particularly suitable for small-batch radioactive source preparation scenarios such as laboratories and small preparation workshops, reducing equipment and maintenance costs. Furthermore, the operator can stand on one side of the pressure frame to operate, reducing the risk of close contact with the electrodeposition tank 20 and the electrolyte, thus improving operational safety.

[0062] The radioactive source-assisted electrodeposition apparatus provided by the present invention is described below. The radioactive source-assisted electrodeposition apparatus described below can be referred to in correspondence with the radioactive source-assisted electrodeposition pressure frame described above.

[0063] Reference Figure 2A radioactive source-assisted electrodeposition apparatus includes a radioactive source-assisted electrodeposition pressure frame provided in any of the above examples, and an electrodeposition tank 20 supported on a source platform 110; the pressing end 120 of the pressure mechanism 12 moves toward or away from the support surface to press or release the electrodeposition tank 20.

[0064] In detail, refer to Figure 4 and Figure 5 The electrodeposition tank 20 has an open first end 21 and a second end 22, and includes a first tank body 201, a second tank body 202, and a third tank body 203 arranged sequentially from the first end 21 to the second end 22. The first tank body 201 is larger than the second tank body 202, forming a first step 204 for supporting the metal anode. The third tank body 203 is larger than the second tank body 202, forming a second step 205 for fixing the radioactive source sheet to the source stage 110. An annular sealing gasket can be provided at the second end 22 of the electrodeposition tank 20 to ensure sealing performance when the electrodeposition tank 20 is crimped.

[0065] It is understood that, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples.

[0066] The radiation source-assisted electrodeposition pressure frame and device provided in this embodiment of the invention, through the cooperation of the drive mechanism 14 and the transmission mechanism 13, drives the pressing end 120 of the pressure mechanism 12 to move closer to or away from the support surface of the source platform 110, thereby conveniently and quickly realizing the pressing and sealing or loosening and disassembling of the electrodeposition reaction tank. This eliminates the need for operators to use specific tools to tighten or loosen multiple screws one by one, simplifying the operation process, shortening the operation time of a single operation, reducing labor intensity, and effectively improving the operational efficiency in small-batch, multi-batch preparation scenarios. Furthermore, operators do not need to frequently bend over to install or remove screws, reducing the risk of close contact with the electrodeposition tank 20 and the electrolyte, thus improving operational safety. In addition, replacing the traditional connection method of multiple screws with a pressing and sealing method avoids uneven force distribution during the tightening of multiple screws, thereby reducing the risk of electrolyte leakage. Simultaneously, it also avoids problems such as stripped threads and thread damage caused by frequent screw installation and removal during long-term use, further reducing the risk of electrolyte leakage, improving the reliability and safety of the device, and reducing maintenance costs.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
