Description

Technical Field

[0001] This application relates to the field of CT equipment assembly, and more specifically, to a shaping device and method for an AD conversion plate of a CT detector. Background Technology

[0002] The CT detector is one of the core components of a computed tomography (CT) scanner. It is responsible for converting the attenuated X-ray signal after it passes through the human body into an electrical signal, which is then processed by a computer to generate a tomographic image. A CT detector module typically consists of a collimator, a scintillator, a photodiode, and an analog-to-digital converter (AD / AD) board. The AD / AD board is constructed by mounting an AD converter onto a dedicated printed circuit board (PCB). The AD / AD converter converts the analog electronic signal output from the photodiode into a data signal, providing processable data for subsequent image reconstruction. CT detectors are pixel-based detectors; high-row CT detector modules typically have thousands of pixels, each corresponding to a signal channel. Because CT detectors are space-constrained and require a minimal size, the AD / AD board PCB is generally designed and manufactured using a high-density flexible PCB, facilitating bending and assembly within the detector's compact structure.

[0003] In the existing technology, AD conversion boards have the following two problems in use: During assembly, the AD conversion board is manually bent, which may cause damage to the internal wiring due to bending stress caused by different assembly methods, resulting in signal breakage and product failure; During assembly, deformation and bulging outside the detector may cause scratches to adjacent detector components, resulting in short circuits and open circuits, leading to product failure. Summary of the Invention

[0004] The main objective of this application is to provide a shaping device and method for an AD conversion plate of a CT detector, so as to solve the technical problem that the AD conversion plate in the prior art relies on manual bending and shaping, which easily causes random stress damage and deformation bulging on the AD conversion plate.

[0005] To achieve the above objectives, a first aspect of this application provides a shaping device for an AD conversion plate of a CT detector, comprising: Base; A first shaping component is disposed on the base, and the side of the first shaping component is a first shaping surface; The first positioning part is used to connect with the auxiliary reinforcement plate at the first end of the AD conversion board to position the auxiliary reinforcement plate at the first end. The second positioning part is used to connect with the auxiliary reinforcement plate at the second end of the AD conversion board to position the auxiliary reinforcement plate at the second end. A second shaping component is disposed on the base and opposite to the first shaping component. The second shaping component has a second shaping surface opposite to the first shaping surface. The second shaping surface can be driven to move toward the first shaping surface. The AD conversion plate is extruded and shaped by the cooperation of the first shaping surface and the second shaping surface.

[0006] Through the above setup, on the one hand, the first shaping surface of the first shaping component and the second shaping surface of the second shaping component cooperate to achieve mechanical extrusion shaping of the AD conversion board, completely replacing the traditional manual bending operation. Compared with the uneven force and angle deviation problems of manual bending, the extrusion force of the shaping surface is evenly distributed in the bending area of ​​the AD conversion board, which can precisely control the bending angle and stress distribution, avoiding micro-cracks, peeling or breakage of the internal trace metal layer caused by local stress concentration. This fundamentally ensures the structural integrity of the signal and power lines, and eliminates functional failures such as signal interruption and transmission interference caused by differences in manual operation. At the same time, the first positioning part and the second positioning part accurately position the auxiliary reinforcement plates at both ends of the AD conversion board, ensuring that the AD conversion board always maintains the preset posture during the shaping process, avoiding bending position deviation caused by board body offset, and further reducing the risk of trace damage. After shaping, the internal stress of the AD conversion board is evenly released, and it will not be damaged by vibration, temperature changes or other factors in subsequent use, significantly improving the stability of circuit operation.

[0007] On the other hand, through mechanical extrusion shaping, the AD conversion board forms a stable bending shape between the preset first and second shaping surfaces. The shaped board structure has increased rigidity, effectively resisting the material's own elastic recovery force and avoiding deformation and bulging problems caused by stress release after traditional manual bending. The shaped AD conversion board fits tightly into the internal installation space of the CT detector, without protruding from the detector's exterior, completely eliminating the possibility of physical friction with adjacent components. Simultaneously, it avoids scratches on the AD conversion board's surface insulation layer and exposed metal traces caused by friction, preventing short circuits between different lines. Furthermore, it eliminates open circuits caused by exposed traces contacting the grounding structure or damage to adjacent components, fundamentally solving the circuit failure problem caused by friction and significantly reducing product scrap rates and maintenance costs.

[0008] On the other hand, the precise positioning of the auxiliary reinforcement plates at both ends of the AD conversion plate by the first and second positioning parts, combined with the standardized extrusion shaping of the shaping surface, ensures that the bending angle and external dimensions of each AD conversion plate are highly consistent, completely avoiding individual differences caused by manual operation and significantly improving the standardization and consistency of CT detector assembly.

[0009] Mechanized shaping operations do not rely on the experience and skills of operators, simplifying the assembly process, shortening the shaping time of a single AD conversion board, and effectively improving production efficiency. At the same time, it reduces rework and repairs caused by manual operation errors, lowers the difficulty of quality control and labor costs in the production process, and is conducive to achieving large-scale production.

[0010] Optionally, the shaping device further includes a signal input component and a signal reading component. The signal input component is used to input an electrical signal to the first end of the shaped AD converter board, and the signal reading component is used to read the output electrical signal of the second end of the shaped AD converter board.

[0011] With the above setup, on the one hand, the signal input component inputs a preset electrical signal (such as an analog signal, test pulse signal, etc.) to the first end of the shaped AD converter board, and the signal reading component simultaneously acquires the output signal at the second end. By comparing the amplitude, waveform, transmission delay, and other parameters of the input and output signals, it is possible to accurately determine whether there are hidden damages such as microcracks, peeling, and open circuits in the internal wiring of the AD converter board. Compared with the limitations of existing technologies that rely solely on visual inspection after shaping (visual inspection cannot identify micro-damage in internal wiring), this device can immediately complete circuit function screening after the shaping process, preventing products with hidden damage caused by uneven stress distribution, positioning deviation, or other potential factors during the shaping process from flowing into subsequent assembly stages. This eliminates detector malfunctions caused by hidden damage from the source and significantly improves the product qualification rate.

[0012] On the other hand, if the signal reading component detects an abnormal output signal (such as signal attenuation, open circuit, distortion, etc.), it can confirm the existence of problems such as excessive bending stress or positioning offset during the shaping process. This allows operators to adjust the extrusion pressure, shaping angle, or fixed position of the positioning part of the first / second shaping surface in real time, achieving dynamic calibration of the shaping process parameters. Through the closed-loop control of "shaping-detection-calibration," the problem of poor product consistency caused by process parameter deviations in mass production can be avoided, ensuring that the shaping effect of each AD conversion board meets the circuit transmission requirements, further improving the stability and repeatability of product quality. Furthermore, by integrating the signal detection function with the shaping function, detection can be carried out directly after the shaping process without transfer. This not only saves the investment in separate detection processes and equipment but also avoids the risk of secondary damage during transfer, significantly simplifying the production process, reducing labor, equipment, and time costs, and adapting to the efficiency requirements of large-scale production.

[0013] Optionally, the signal input component includes a moving member and a signal input circuit board, the signal input circuit board having a plurality of signal pins, the moving member being connected to the signal input circuit board for driving the signal input circuit board to be electrically connected to a first end of the AD converter board through the signal pins.

[0014] With the above setup, the moving component is directly connected to the signal input circuit board. The movement trajectory, docking position, and contact pressure of the signal input circuit board can be precisely controlled by mechanical drive. On the one hand, it ensures that multiple signal pins are precisely aligned with the corresponding interfaces (such as pads, pin headers, signal contacts, etc.) at the first end of the AD conversion board, avoiding problems such as pin offset and misconnection caused by visual deviation and operational jitter during manual docking, and ensuring that each signal pin can achieve effective electrical contact. On the other hand, by adjusting the driving force of the moving component, the contact pressure between the pin and the interface can be controlled within a reasonable range (meeting the electrical connection conduction requirements while avoiding excessive pressure that could cause deformation of the AD conversion board interface or bending damage to the pin). This ensures the stability of the electrical connection from both the docking position and contact pressure dimensions, avoiding detection errors such as signal transmission interruption and distortion caused by poor contact.

[0015] On the other hand, the signal input circuit board integrates multiple signal pins, which can simultaneously achieve one-to-one electrical connection with multiple signal channels (such as analog signal input channels, power channels, ground channels, control signal channels, etc.) at the first end of the AD conversion board. Compared with the traditional single-channel sequential docking test method, this design can complete the synchronous input of multiple signals in a single docking process, which significantly shortens the signal input operation time and improves the overall testing efficiency. At the same time, it can cover the core signal channels of the AD conversion board at one time, realizing comprehensive testing of circuit integrity and signal transmission performance (such as synchronously verifying power stability, analog signal transmission consistency, control signal response timeliness, etc.), avoiding hidden defects caused by single-channel testing omissions (such as micro-damage to a certain trace not being detected), and further ensuring the comprehensiveness and accuracy of the test results.

[0016] Optionally, the first shaping component includes a first unit, which is fixed to the base, and the first shaping surface is provided on one side of the first unit; The first positioning part is located at the upper end of the first unit, and the second positioning part is located at the lower part of the first unit and on the same side as the first shaping surface.

[0017] With the above configuration, the first positioning part (upper end) and the second positioning part (lower end) are distributed along the same side of the first unit, and both are positioned for the auxiliary reinforcing plates at both ends of the AD conversion plate, forming a positioning structure of "two-way vertical and same-side limiting": On the one hand, a fixing force can be applied from both ends of the AD conversion plate to ensure that the plate is always in close contact with the first shaping surface during the shaping process, avoiding bending position deviation caused by positioning offset (such as bending point deviating from the preset area), thereby preventing additional stress concentration of internal wiring due to incorrect bending position; on the other hand, the same-side layout makes the positioning force and the supporting force of the first shaping surface in the same direction, which can effectively offset the lateral force generated when the second shaping surface is squeezed, avoiding lateral displacement or torsion of the AD conversion plate during the squeezing process, ensuring that the bending angle and external dimensions of the plate after shaping are fully adapted to the internal installation space of the CT detector, and eliminating deformation and bulging problems from the perspective of posture control.

[0018] Optionally, the first positioning part includes two clamping members disposed opposite to each other, at least one of the clamping members being movable relative to the first unit along a first direction, the first direction being the width direction of the auxiliary reinforcing plate at the first end of the AD conversion board, so that the two clamping members clamp and position the auxiliary reinforcing plate at the first end along the first direction.

[0019] With the above configuration, the two clamping members are positioned opposite each other along the width direction of the auxiliary reinforcing plate at the first end of the AD conversion plate. The movement of at least one clamping member achieves clamping and fixing of the auxiliary reinforcing plate, applying uniform clamping force from both lateral sides of the plate, thus stably limiting the plate to a preset positioning position. Compared to traditional single-positioning or non-width-direction positioning methods, this design effectively prevents the auxiliary reinforcing plate from shifting along the width direction during the shaping process, thereby preventing the overall posture of the AD conversion plate from becoming skewed. Simultaneously, precise clamping and positioning ensures that the fit between the first end of the AD conversion plate and the first shaping surface meets preset requirements, providing a precise reference posture for the extrusion shaping of the second shaping component. This avoids deviations in the plate's posture leading to bending angles and dimensions that do not meet design standards after shaping, reducing shaping errors from the outset.

[0020] On the other hand, the clamping operation of this positioning structure is simple and convenient. The operator only needs to place the auxiliary reinforcing plate at the first end of the AD conversion board between the two clamping parts, and the clamping and positioning can be quickly completed by driving the movable clamping parts. After the shape is set, the positioning can be released by moving the clamping parts in the opposite direction, which facilitates quick loading and unloading of the AD conversion board. Compared with complicated bolt fixing and snap-on positioning methods, this design greatly simplifies the clamping and disassembly process, shortens the positioning operation time of a single product, and effectively improves the overall production efficiency.

[0021] Furthermore, the first positioning part is located at the upper end of the first unit, and its clamping direction is adapted to the width direction of the auxiliary reinforcing plate. This layout works in concert with the first shaping surface and the second positioning part of the first unit. After precise positioning, the first end of the AD conversion plate is stably connected to the first positioning part through the auxiliary reinforcing plate, and the second end of the auxiliary reinforcing plate is simultaneously positioned through the second positioning part. This ensures that the AD conversion plate can be precisely fitted along the first shaping surface as a whole after being compressed, ensuring that the force direction and stress distribution of the plate meet the design expectations when the second shaping component is squeezed, further improving the consistency and stability of the shaping effect.

[0022] Optionally, the second positioning part includes a tension spring, the lower end of which is connected to the base, and the upper end of which is used to connect to the reinforcing plate at the second end of the AD conversion plate to apply a downward tensile force to the AD conversion plate.

[0023] With the above settings, on the one hand, the downward tensile force applied by the tension spring can form a continuous longitudinal constraint on the second end reinforcing plate of the AD conversion plate. In conjunction with the first positioning part clamping and positioning the upper end of the first end reinforcing plate of the AD conversion plate, the AD conversion plate as a whole forms a longitudinal force balance state of upper end clamping and lower end stretching, providing a stable posture for subsequent extrusion and shaping.

[0024] On the other hand, the tension spring has elastic deformation characteristics, and the tensile force it applies can adaptively adjust with the slight displacement of the AD conversion plate, rather than being a rigid positioning force. When the AD conversion plate undergoes slight deformation due to compression during the shaping process, the tension spring can buffer the stress through its own elastic expansion and contraction, avoiding excessive rigid tension on the second-end reinforcing plate and preventing the reinforcing plate from deforming, cracking, or peeling off from the AD conversion plate body. At the same time, the adaptive elastic force can prevent the tensile force from being concentrated on a local area of ​​the AD conversion plate, protecting the internal wiring of the plate from damage by additional tensile force. Compared with the traditional rigid positioning method, this significantly improves product protection during the positioning process and reduces the product scrap rate in the positioning stage.

[0025] On the other hand, the first positioning part achieves lateral clamping and positioning along the width direction of the reinforcing plate, restricting the lateral displacement of the plate; the second positioning part, with its tension spring along the longitudinal direction, achieves longitudinal tension positioning, restricting the longitudinal warping and detachment of the plate. Together, they construct a three-dimensional positioning system of "lateral clamping + longitudinal tension". This system can resist the complex forces such as lateral force and torsional force generated during the extrusion and shaping by the second shaping component, effectively avoiding posture deviations such as lateral slippage, longitudinal warping, or overall torsion of the AD conversion plate during the shaping process, ensuring that the plate always maintains the preset positioning posture.

[0026] Optionally, a pressure sensor is provided on the first unit, the pressure sensor being used to detect the pressure applied to the AD conversion board by the second shaping surface.

[0027] With the above settings, the extrusion pressure on the AD conversion plate can be detected in real time during the extrusion and shaping process to ensure the shaping effect of the AD conversion plate and avoid damage to the AD conversion plate due to excessive pressure.

[0028] Optionally, the second shaping component includes a second unit, a heating unit, and a pressure unit. The heating unit is fixed between the pressure unit and the second unit, and the pressure unit is located between the heating unit and the first unit. The pressure unit has a second shaping surface on the side facing the first unit. The heating unit is used to transfer heat to the heating unit and the pressure unit is used to transfer heat to the AD conversion plate.

[0029] Through the above configuration, the heating unit transfers heat to the AD conversion board via the pressure unit, enabling the AD conversion board (especially the PCB substrate and internal trace metal layers) to exhibit better flexibility and plasticity at a preset temperature. At this temperature, the compressive force applied by the pressure unit can be more evenly distributed across the board, avoiding localized stress concentration caused by excessive material rigidity during cold pressing. In a hot environment, the ductility of the internal trace metal layers is improved, making it less prone to microcracks or peeling during bending. Simultaneously, the stress relaxation effect of the substrate material reduces residual internal stress after shaping, preventing secondary damage to the traces due to stress release during subsequent use. This further ensures circuit integrity from a process perspective, resolving reliability issues caused by residual stress from traditional cold pressing.

[0030] The heating unit is fixed between the pressure unit and the second unit, forming a stable heat conduction path of "second unit → heating unit → pressure unit → AD conversion plate". The second unit provides rigid support for the heating unit, avoiding uneven heat distribution caused by structural deformation during the heating process. The heating unit is directly attached to the pressure unit, which has high heat conduction efficiency and can make the second shaping surface of the pressure unit form a uniform temperature field, thereby uniformly transferring heat to the shaping area of ​​the AD conversion plate.

[0031] Optionally, the base may also include a drive assembly disposed thereon, the drive assembly being configured to drive the second unit toward and away from the first unit.

[0032] According to another aspect of this application, a method for shaping a CT detector AD conversion plate is provided, wherein the shaping operation is performed using the above-described shaping device, the shaping operation including: The auxiliary reinforcing plate at the first end of the AD conversion board is installed to the first positioning part and positioned by the first positioning part; The AD conversion plate is bent downwards along the preset bending position, so that the AD conversion plate is bent to be opposite to the first shaping surface of the first shaping component; After bending, the reinforcing plate at the second end of the AD conversion plate is connected to the second positioning part, and positioned by the second positioning part; The heating unit is controlled to preheat the pressure unit to a preset temperature; The second unit controls the pressure application unit to move synchronously toward the first shaping surface, and the second shaping surface and the first shaping surface of the pressure application unit cooperate to apply pressure to the AD conversion plate; The pressure P applied to the AD conversion plate by the pressure sensor is obtained. When the pressure P reaches the preset pressure value, the pressure unit moves backward after the second shaping surface is held for a preset time T. The signal input component and the signal reading component are respectively connected to the first end and the second end of the AD conversion board, and the signal input component is controlled to input an electrical signal to the first end of the AD conversion board. The signal reading component receives and analyzes the electrical signal received from the second end of the AD converter board to determine whether the AD converter board is functioning normally after the design is finalized.

[0033] Through the above setup, from the precise positioning of the first reinforcing plate at the AD converter board, to the standardized bending along the preset bending position, and then to the positioning and fixing of the second reinforcing plate, each step relies on the positioning structure of the device to achieve mechanical limiting, avoiding problems such as bending angle deviation and positioning offset caused by manual operation. Simultaneously, key parameters such as heating preheating temperature, applied pressure, and holding time are all precisely controlled by the device, ensuring that each AD converter board completes its shape under the same process conditions. This standardized design significantly improves the consistency of AD converter board shaping in mass production, maintaining a high degree of uniformity in the bending shape, dimensional tolerances, and stress distribution of the finished products.

[0034] A step-by-step positioning logic of "first positioning the first end → then bending → finally positioning the second end" is adopted to form a positioning closed loop of "two-way constraint at both ends": First, the first end reinforcement plate is fixed by the first positioning part, providing a stable reference for bending and preventing overall board displacement during bending; second, bending is performed along a preset position to ensure the accuracy of the bend point's fit with the first shaping surface, reducing local stress concentration caused by bending position deviations in internal traces; third, the second end reinforcement plate is fixed, working with the first positioning part to form a longitudinal tensile constraint, forcing the board to fit tightly against the first shaping surface. This step-by-step collaborative design ensures, from an attitude control perspective, that the AD conversion board will not warp or detach from the shaping surface during subsequent hot pressing and shaping, further reducing the risk of micro-cracks and breakage of internal traces due to attitude deviations, and ensuring circuit integrity.

[0035] The hot-pressing process, characterized by "preheating-precise pressure application-pressure holding," is designed to perfectly match the structural depth of the second shaping component, achieving a synergistic effect of "thermoplastic deformation + stress release." First, the heating unit preheats the pressure application unit to a preset temperature, bringing the AD conversion plate substrate material into a thermoplastic state, improving material plasticity and reducing stress concentration during cold extrusion. Then, the second unit drives the pressure application unit to precisely move and apply pressure, with pressure sensors enabling closed-loop pressure control. This ensures the pressure applied to the AD conversion plate remains stable at a preset value, preventing damage from overpressure or insufficient shaping from underpressure. Finally, the holding time T provides sufficient time for stress release within the AD conversion plate, reducing residual stress. This process allows the AD conversion plate to undergo stable plastic deformation after cooling, significantly reducing the risk of deformation and bulging due to material elastic rebound, ensuring a perfect fit between the shaped plate and the internal installation space of the CT detector.

[0036] After the shaping process is completed, the signal detection step is directly connected. Through the collaboration of the signal input component and the signal reading component, the "shaping effect - circuit function" is verified simultaneously: a preset electrical signal is input to the first end of the AD conversion board, and the output signal of the second end is read and analyzed. This allows for accurate determination of whether there are hidden damages to the internal wiring or abnormal signal transmission in the board after shaping. Compared with the traditional "shaping and detection separation" mode, this integrated design avoids the risk of defective products being transferred to subsequent assembly stages, improving the product qualification rate from the source. At the same time, the detection results can be fed back to optimize the shaping process parameters (such as heating temperature and pressure), forming a quality closed loop of "shaping-detection-calibration", further improving the stability of overall production quality.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] To solve related technical problems, such as Figure 1 As shown, this embodiment provides a shaping device for a CT detector AD conversion plate 6, comprising: The base 1, serving as the basic structure of the shaping device, supports and mounts various components. The base 1 can be made of various types of materials or a metal platform, etc. A first shaping component 2 and a second shaping component 3 are mounted on the base 1. The first shaping component 2 can be fixed relative to the base 1, while the second shaping component 3 can move linearly relative to the base 1, including directions towards and away from the first shaping component 2. The opposing surfaces of the first shaping component 2 and the second shaping component 3 are respectively provided with a first shaping surface 21 and a second shaping surface 31. When the second shaping component 3 moves closer to the first shaping component 2, the second shaping surface 31 moves closer to the first shaping surface 21. The first shaping surface 21 and the second shaping surface 31 have outer contours that match the shaped state of the AD conversion plate 6, thus enabling them to cooperate and compress each other to cause the AD conversion to produce the desired deformation and achieve the desired shape.

[0045] Before shaping, the AD conversion plate 6 needs to be positioned. Therefore, this embodiment also includes a first positioning part 4 and a second positioning part 5. The first positioning part 4 and the second positioning part 5 are respectively used to position the reinforcing plate 50 at the first end and the reinforcing plate 61 at the second end of the AD conversion plate 6. The first end is a tungsten carbide reinforcing plate, and the second end is an FR4 reinforcing plate. The shaping process mainly involves applying extrusion pressure to the portion located between the tungsten carbide reinforcing plate and the second reinforcing plate to deform it. The shaped AD conversion plate 6 is as follows: Figure 2 As shown.

[0046] In this embodiment, through the above-mentioned configuration, on the one hand, the first shaping surface 21 of the first shaping component 2 and the second shaping surface 31 of the second shaping component 3 cooperate to achieve mechanical extrusion shaping of the AD conversion board 6, completely replacing the traditional manual bending operation. Compared with the problems of uneven force and angle deviation in manual bending, the extrusion force of the shaping surface is evenly distributed in the bending area of ​​the AD conversion board 6, which can accurately control the bending angle and stress distribution, avoiding micro-cracks, peeling or breakage of the internal wiring metal layer caused by local stress concentration. This fundamentally ensures the structural integrity of the signal line and power line, and eliminates functional failures such as signal disconnection and transmission interference caused by differences in manual operation. At the same time, the first positioning part 4 and the second positioning part 5 accurately position the auxiliary reinforcing plates at both ends of the AD conversion board 6, ensuring that the AD conversion board 6 always maintains the preset posture during the shaping process, avoiding bending position deviation caused by board body offset, and further reducing the risk of wiring damage. After the AD conversion board 6 is shaped, the internal stress is released evenly, and it will not suffer secondary damage due to factors such as vibration and temperature changes during subsequent use, which significantly improves the stability of circuit operation.

[0047] On the other hand, through mechanical extrusion shaping, the AD conversion board 6 forms a stable bending shape between the preset first shaping surface 21 and the second shaping surface 31. The rigidity of the shaped board structure is enhanced, effectively resisting the elastic recovery force of the material itself and avoiding the deformation and bulging problems caused by stress release after traditional manual bending. The shaped AD conversion board 6 can fit tightly into the internal installation space of the CT detector and will not protrude from the outside of the detector, completely eliminating the possibility of physical scratches with adjacent components. At the same time, it avoids scratches on the surface insulation layer of the AD conversion board 6 and exposure of metal traces caused by scratches, preventing short circuits between different lines; on the other hand, it eliminates the possibility of open circuits caused by contact between exposed traces and grounding structures or damage to adjacent components, fundamentally solving the problem of circuit failure caused by scratches, and significantly reducing product scrap rate and maintenance costs.

[0048] On the other hand, the precise positioning of the auxiliary reinforcing plates at both ends of the AD conversion plate 6 by the first positioning part 4 and the second positioning part 5, combined with the standardized extrusion shaping of the shaping surface, ensures that the bending angle and external dimensions of each AD conversion plate 6 are highly consistent, completely avoiding individual differences caused by manual operation, and significantly improving the standardization and consistency of CT detector assembly.

[0049] Mechanized shaping operations do not rely on the experience and skills of operators, simplifying the assembly process, shortening the shaping time of a single AD conversion board 6, and effectively improving production efficiency. At the same time, it reduces rework and repairs caused by manual operation errors, lowers the difficulty of quality control and labor costs in the production process, and is conducive to achieving large-scale production.

[0050] In one implementation, such as Figure 1 As shown, the shaping device also includes a signal input component 11 and a signal reading component 12. The signal input component 11 is used to input an electrical signal to the first end of the shaped AD converter board 6, and the signal reading component 12 is used to read the output electrical signal of the second end of the shaped AD converter board 6.

[0051] With the above setup, on the one hand, the signal input component 11 inputs a preset electrical signal (such as an analog signal, a test pulse signal, etc.) to the first end of the shaped AD conversion board 6, and the signal reading component 12 simultaneously collects the output signal from the second end. By comparing the amplitude, waveform, transmission delay, and other parameters of the input and output signals, it is possible to accurately determine whether there are hidden damages such as microcracks, peeling, or open circuits in the internal wiring of the AD conversion board 6. Compared with the limitations of the existing technology that "relies only on visual inspection after shaping" (the appearance cannot identify micro-damage to internal wiring), this device can immediately complete the circuit function screening after the shaping process, avoiding the flow of products with hidden damage caused by potential factors such as uneven stress distribution and positioning deviation during the shaping process into the subsequent assembly stage. This eliminates detector malfunctions caused by hidden damage from the source and significantly improves the product qualification rate.

[0052] On the other hand, if the signal reading component 12 detects an abnormal output signal (such as signal attenuation, open circuit, distortion, etc.), it can confirm that there are problems such as excessive bending stress or positioning offset during the shaping process. This allows operators to adjust the extrusion force, shaping angle, or fixed position of the positioning part of the first / second shaping surface 31 in real time, achieving dynamic calibration of the shaping process parameters. Through the closed-loop control of "shaping-detection-calibration," the problem of poor product consistency caused by process parameter deviations in mass production can be avoided, ensuring that the shaping effect of each AD conversion board 6 meets the circuit transmission requirements, further improving the stability and repeatability of product quality. Furthermore, by integrating the signal detection function with the shaping function, detection can be carried out directly after the shaping process is completed without transfer. This not only saves the investment in separate detection processes and equipment but also avoids the risk of secondary damage during transfer, significantly simplifying the production process, reducing labor, equipment, and time costs, and adapting to the efficiency requirements of large-scale production.

[0053] In one implementation, such as Figure 1 As shown, the signal input component 11 includes a moving member 10 and a signal input circuit board. The signal input circuit board has a plurality of signal pins. The moving member 10 is connected to the signal input circuit board and is used to drive the signal input circuit board to be electrically connected to the first end of the AD conversion board 6 through the signal pins.

[0054] With the above configuration, the moving component 10 is directly connected to the signal input circuit board. The movement trajectory, docking position, and contact pressure of the signal input circuit board can be precisely controlled by mechanical drive. On the one hand, it can ensure that multiple signal pins are precisely aligned with the corresponding interfaces (such as pads, pin headers, signal contacts, etc.) at the first end of the AD conversion board 6, avoiding problems such as pin offset and misconnection caused by visual deviation and operation jitter during manual docking, and ensuring that each signal pin can achieve effective electrical contact. On the other hand, by adjusting the driving force of the moving component 10, the contact pressure between the pin and the interface can be controlled within a reasonable range (meeting the electrical connection conduction requirements while avoiding excessive pressure that could cause deformation of the AD conversion board 6 interface or bending and damage to the pin). The stability of the electrical connection is ensured from both the docking position and contact pressure dimensions, avoiding detection errors such as signal transmission interruption and distortion caused by poor contact.

[0055] On the other hand, the signal input circuit board integrates multiple signal pins, which can simultaneously achieve one-to-one electrical connection with multiple signal channels (such as analog signal input channel, power supply channel, ground channel, control signal channel, etc.) at the first end of the AD conversion board 6. Compared with the traditional single-channel sequential docking test method, this design can complete the synchronous input of multiple signals in a single docking process, which significantly shortens the signal input operation time and improves the overall testing efficiency. At the same time, it can cover the core signal channels of the AD conversion board 6 at one time, realizing comprehensive testing of circuit integrity and signal transmission performance (such as synchronously verifying power supply stability, analog signal transmission consistency, control signal response timeliness, etc.), avoiding hidden defects caused by single-channel testing omissions (such as micro-damage to a certain trace not being detected), and further ensuring the comprehensiveness and accuracy of the test results.

[0056] In one implementation, such as Figure 1 As shown, a fixed arm 14 is mounted on the base 1. The upper end of the fixed arm 14 is located above the first shaping component 22 and is provided with a moving component 10. The moving component 10 includes a moving push rod, and a signal input circuit board is mounted on the lower end of the moving push rod. The moving push rod drives the signal input circuit board to move downward and electrically connect to the first end of the AD conversion board 6 to realize signal input. It also drives the input circuit board to move upward and separate it from the AD conversion board 6.

[0057] In one implementation, such as Figure 1 As shown, the first shaping component 2 includes a first unit 20, which is fixed to the base 1, and the first shaping surface 21 is provided on one side of the first unit 20. The first positioning part 4 is located at the upper end of the first unit 20, and the second positioning part 5 is located at the lower part of the first unit 20 and on the same side as the first shaping surface 21.

[0058] With the above configuration, the first positioning part 4 (upper end) and the second positioning part 5 (lower end) are distributed along the same side of the first unit 20, and both are positioned for the auxiliary reinforcing plates at both ends of the AD conversion plate 6, forming a positioning structure of "two-way vertical and same-side limiting": On the one hand, a fixing force can be applied from both ends of the longitudinal direction of the AD conversion plate 6 to ensure that the plate is always in close contact with the first shaping surface 21 during the shaping process, avoiding bending position deviation caused by positioning offset (such as bending point deviating from the preset area), thereby preventing additional stress concentration of internal wiring due to incorrect bending position; on the other hand, the same-side layout makes the positioning force and the support force of the first shaping surface 21 in the same direction, which can effectively offset the lateral force generated when the second shaping surface 31 is squeezed, avoiding lateral displacement or torsion of the AD conversion plate 6 during the squeezing process, ensuring that the bending angle and external dimensions of the plate after shaping are fully adapted to the internal installation space of the CT detector, and eliminating the problem of deformation and bulging from the perspective of posture control.

[0059] In one embodiment, the first positioning part 4 includes two clamping members disposed opposite to each other. At least one of the clamping members can move relative to the first unit 20 along a first direction. The first direction is the width direction of the auxiliary reinforcing plate 60 at the first end of the AD conversion plate 6, so that the two clamping members clamp and position the auxiliary reinforcing plate 60 at the first end along the first direction. The two clamping members can be driven by a cylinder or manually rotated by a screw.

[0060] With the above configuration, the two clamping members are positioned opposite each other along the width direction of the auxiliary reinforcing plate at the first end of the AD conversion plate 6. The movement of at least one clamping member achieves clamping and fixing of the auxiliary reinforcing plate, applying uniform clamping force from both lateral sides of the auxiliary reinforcing plate, thus stably limiting the auxiliary reinforcing plate to a preset positioning position. Compared with traditional single-limiting or non-width-direction positioning methods, this design effectively avoids the auxiliary reinforcing plate shifting along the width direction during the shaping process, thereby preventing the overall posture of the AD conversion plate 6 from becoming skewed. At the same time, precise clamping and positioning ensures that the fit between the first end of the AD conversion plate 6 and the first shaping surface 21 meets the preset requirements, providing a precise reference posture for the extrusion shaping of the second shaping component 3, avoiding the bending angle and external dimensions after shaping not meeting design standards due to plate posture deviation, and reducing shaping errors from the source.

[0061] On the other hand, the clamping operation of this positioning structure is simple and convenient. The operator only needs to place the auxiliary reinforcing plate 60 at the first end of the AD conversion board 6 between the two clamping parts, and the clamping and positioning can be quickly completed by driving the movable clamping parts. After the shape is set, the positioning can be released by moving the clamping parts in the opposite direction, which facilitates quick picking and putting away of the AD conversion board 6. Compared with complex bolt fixing and snap-on positioning methods, this design greatly simplifies the clamping and disassembly process, shortens the positioning operation time of a single product, and effectively improves the overall production efficiency.

[0062] Furthermore, the first positioning part 4 is located at the upper end of the first unit 20, and its clamping direction is adapted to the width direction of the reinforcing plate. This layout works in concert with the first shaping surface 21 and the second positioning part 5 of the first unit 20. After precise positioning, the first end of the AD conversion plate 6 is stably connected to the first positioning part 4 through the reinforcing plate, and the second end of the reinforcing plate is synchronously positioned through the second positioning part 5. This ensures that the AD conversion plate 6 can be precisely fitted along the first shaping surface 21 as a whole after being compressed, ensuring that the force direction and stress distribution of the plate body meet the design expectations when the second shaping component 3 is squeezed, further improving the consistency and stability of the shaping effect.

[0063] In one implementation, such as Figure 1 As shown, the second positioning part 5 includes a tension spring 50. The lower end of the tension spring 50 is connected to the base 1, and the upper end is used to connect to the reinforcing plate 61 at the second end of the AD conversion plate 6 to apply a downward tensile force to the AD conversion plate 6. Two tension springs 50 can be provided and distributed along the width direction of the second end of the AD conversion plate 6. The two tension springs 50 are respectively connected to two parts of the second end of the AD conversion plate 6 to avoid localized stress.

[0064] With the above settings, on the one hand, the downward tensile force applied by the tension spring 50 can form a continuous longitudinal constraint on the second end reinforcing plate of the AD conversion plate 6, and in conjunction with the first positioning part 4 clamping and positioning the upper end of the first end reinforcing plate of the AD conversion plate 6, the AD conversion plate 6 as a whole forms a longitudinal force balance state of upper end clamping and lower end stretching, providing a stable posture for subsequent extrusion and shaping.

[0065] On the other hand, the tension spring 50 has elastic deformation characteristics, and the tensile force it applies can adaptively adjust with the slight displacement of the AD conversion plate 6, rather than being a rigid positioning force. When the AD conversion plate 6 undergoes slight deformation due to compression during the shaping process, the tension spring 50 can buffer the stress through its own elastic expansion and contraction, avoiding excessive rigid tension on the second-end reinforcing plate, and preventing the reinforcing plate from deforming, cracking, or peeling off from the AD conversion plate 6 body. At the same time, the adaptive elastic force can prevent the tensile force from being concentrated on a local area of ​​the AD conversion plate 6, protecting the internal wiring of the plate from damage by additional tensile force. Compared with the traditional rigid positioning method, this significantly improves the product protection during the positioning process and reduces the product scrap rate in the positioning stage.

[0066] On the other hand, the first positioning part 4 achieves lateral clamping and positioning along the width direction of the reinforcing plate, restricting the lateral displacement of the plate; the second positioning part 5, with its tension spring 50, achieves longitudinal stretching and positioning, restricting the longitudinal warping and detachment of the plate. Together, they construct a three-dimensional positioning system of "lateral clamping + longitudinal stretching". This system can resist the complex forces such as lateral force and torsional force generated during the extrusion and shaping by the second shaping component 3, effectively avoiding lateral slippage, longitudinal warping, or overall torsion of the AD conversion plate 6 during the shaping process, ensuring that the plate always maintains the preset positioning posture.

[0067] Two mounting holes can be provided on the auxiliary reinforcing plate 61 at the second end of the AD conversion plate 6 for connecting the tension spring 50.

[0068] In one implementation, such as Figure 1 As shown, a pressure sensor 15 is provided on the first unit 20. The pressure sensor 15 is used to detect the pressure applied to the AD conversion plate 6 by the second shaping surface 31. With the above configuration, the extrusion pressure on the AD conversion plate 6 can be detected in real time during the extrusion shaping process to ensure the shaping effect of the AD conversion plate 6 and avoid damage to the AD conversion plate 6 due to excessive pressure.

[0069] In one implementation, such as Figure 1 As shown, the second shaping component 3 includes a second unit 30, a heating unit 33, and a pressure applying unit 32. A sliding platform 9 can be fixed on the base 1, and the second unit 30 is slidably mounted on the sliding platform 9. The heating unit 33 is fixed between the pressure applying unit 32 and the second unit 30. The pressure applying unit 32 is located between the heating unit 33 and the first unit 20. The side of the pressure applying unit 32 facing the first unit 20 has a second shaping surface 31. The heating unit 33 is used to transfer heat to the heating unit, and the pressure applying unit 32 transfers heat to the AD conversion plate 6.

[0070] Through the above configuration, the heating unit 33 transfers heat to the AD conversion board 6 via the pressure unit 32, enabling the AD conversion board 6 (especially the PCB substrate and internal trace metal layer) to exhibit better flexibility and plasticity at a preset temperature. At this time, the extrusion pressure applied by the pressure unit 32 can act more evenly on the board, avoiding localized stress concentration caused by excessive material rigidity during cold extrusion. In a hot environment, the ductility of the internal trace metal layer is improved, making it less prone to microcracks or peeling during bending. Simultaneously, the stress relaxation effect of the substrate material reduces residual internal stress after shaping, preventing secondary damage to the traces due to stress release during subsequent use. This further ensures circuit integrity from a process perspective, resolving reliability issues caused by residual stress from traditional cold pressing.

[0071] The heating unit 33 is fixed between the pressure unit 32 and the second unit 30, forming a stable heat conduction path of "second unit 30 → heating unit 33 → pressure unit 32 → AD conversion plate 6". The second unit 30 provides rigid support for the heating unit 33, avoiding uneven heat distribution caused by structural deformation during the heating process. The heating unit 33 is directly attached to the pressure unit 32, which has high heat conduction efficiency and can make the second shaping surface 31 of the pressure unit 32 form a uniform temperature field, thereby uniformly transferring heat to the shaping area of ​​the AD conversion plate 6.

[0072] The heating unit 33 can be a heating band composed of electric heating wires, extending from the upper end to the lower end of the pressure unit 32 to achieve uniform heating of the pressure unit 32. A heating control board 13 is installed at the upper end of the second unit 30, and the power of the heating unit 33 is controlled by the heating control board 13. The pressure unit 32 can be made of a material with high thermal conductivity, such as copper, which can quickly conduct heat to the AD conversion board 6.

[0073] In one implementation, such as Figure 1 As shown, the shaping device further includes a drive assembly 7 disposed on the base 1. The drive assembly 7 is configured to drive the second unit 30 to move toward and away from the first unit 20. The drive assembly 7 may include a motion push rod capable of driving the second unit 30 to move linearly on the sliding platform 9.

[0074] To achieve control of the entire shaping process, a motion control module 8, i.e. a motion control PCB board, can also be set on the base 1. The motion control module 8 can control the movement of the second unit 30, the start and stop of the heating unit 33, as well as the heating power and the movement of the moving component 10, thereby automating the shaping process and improving shaping efficiency.

[0075] According to another aspect of this application, a shaping method for a CT detector AD conversion plate 6 is provided, wherein the shaping operation is performed using the above-described shaping device, the shaping operation including: The reinforcing plate 60 at the first end of the AD conversion board 6 is installed onto the first positioning part 4 and positioned by the first positioning part 4. The AD conversion plate 6 is bent downwards along the preset bending position, so that the AD conversion plate 6 is bent to be opposite to the first shaping surface 21 of the first shaping component 22. The bending process can be carried out manually, for example, by using a specific tool to bend along the preset bending position. The AD conversion plate 6 after bending is roughly L-shaped, with its vertical surface located to the right of the first shaping surface 21 and to the left of the second shaping surface 31. After bending, the reinforcing plate 61 at the second end of the AD conversion plate 6 is connected to the second positioning part 5 and positioned by the second positioning part 5; The heating unit 33 is controlled to preheat the pressure unit 32 to a preset temperature; The second unit 30 controls the pressure unit 32 to move synchronously toward the first shaping surface 21, and the second shaping surface 31 and the first shaping surface 21 of the pressure unit 32 cooperate to apply pressure to the AD conversion plate 6. The pressure P applied to the AD conversion plate 6 by the second shaping surface 31 is obtained by the pressure sensor 15. When the pressure P reaches the preset pressure value, the pressure unit 32 moves backward after the second shaping surface 31 is held for a preset time T. The signal input component 11 and the signal reading component 12 are respectively connected to the first end and the second end of the AD conversion board 6, and the signal input component 11 is controlled to input an electrical signal to the first end of the AD conversion board 6. The signal reading component 12 receives and analyzes the electrical signal received from the second end of the AD conversion board 6 to determine whether the AD conversion board 6 is functioning normally after being shaped.

[0076] In this embodiment, through the above-described setup, from the precise positioning of the first-end reinforcing plate of the AD conversion plate 6, to the standardized bending along the preset bending position, and then to the positioning and fixing of the second-end reinforcing plate, each step relies on the positioning structure of the device to achieve mechanical limiting, avoiding problems such as bending angle deviation and positioning offset caused by manual operation. Simultaneously, key parameters such as heating preheating temperature, pressure application, and holding time are precisely controlled by the device, ensuring that each AD conversion plate 6 completes its shaping under the same process conditions. This standardized design significantly improves the shaping consistency of the AD conversion plates 6 in mass production, maintaining a high degree of uniformity in the bending shape, dimensional tolerances, and stress distribution of the finished products.

[0077] The system employs a step-by-step positioning logic of "first positioning the first end → then bending → finally positioning the second end," forming a positioning closed loop with "two-way constraints at both ends." The first step involves fixing the first-end reinforcing plate with the first positioning part 4, providing a stable reference for bending and preventing overall board displacement during the bending process. The second step involves bending along a preset position to ensure accurate contact between the bending point and the first shaping surface 21, reducing localized stress concentration caused by bending position deviations in the internal wiring. The third step involves fixing the second-end reinforcing plate, which, together with the first positioning part 4, forms a longitudinal tensile constraint, forcing the board to tightly conform to the first shaping surface 21. This step-by-step collaborative design ensures, from an attitude control perspective, that the AD conversion board 6 will not warp or detach from the shaping surface during subsequent hot-pressing and shaping processes, further reducing the risk of micro-cracks and breakage of internal wiring due to attitude deviations, and ensuring circuit integrity.

[0078] The hot-pressing process design of "preheating-precise pressure application-pressure holding" during the shaping process is adapted to the structural depth of the second shaping component 3, achieving a synergistic effect of "thermoplastic deformation + stress release": First, the heating unit 33 preheats the pressure application unit 32 to a preset temperature, causing the substrate material of the AD conversion plate 6 to enter a thermoplastic state, improving the material's plasticity and reducing stress concentration during cold extrusion; then, the second unit 30 drives the pressure application unit 32 to precisely move and apply pressure, and the pressure sensor 15 achieves closed-loop pressure control, ensuring that the pressure applied to the AD conversion plate 6 is stable at the preset value, avoiding plate damage caused by overpressure or insufficient shaping caused by underpressure; finally, by setting the pressure holding time T, sufficient time is provided for the internal stress of the AD conversion plate 6 to release stress, reducing residual stress. This process allows the AD conversion plate 6 to form stable plastic deformation after cooling, significantly reducing the risk of deformation and bulging caused by material elastic rebound, and ensuring that the shaped form after shaping is completely adapted to the internal installation space of the CT detector.

[0079] After the shaping process is completed, the signal detection step is directly connected. Through the collaboration of the signal input component 11 and the signal reading component 12, the "shaping effect - circuit function" is verified synchronously: a preset electrical signal is input to the first terminal of the AD conversion board 6, and the output signal of the second terminal is read and analyzed. This allows for accurate determination of whether there are hidden damages to the internal wiring or abnormal signal transmission in the board after shaping. Compared with the traditional "shaping and detection separation" mode, this integrated design avoids the risk of defective products being transferred to subsequent assembly stages, improving the product qualification rate from the source. At the same time, the detection results can be fed back to optimize the shaping process parameters (such as heating temperature and pressure), forming a quality closed loop of "shaping-detection-calibration", further improving the stability of the overall production quality.

[0080] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0081] Obviously, those skilled in the art should understand that the various units or steps of this application described above can be implemented using general-purpose computing devices. They can be centralized on a single computing device or distributed across a network of multiple computing devices. Optionally, they can be implemented using computer-executable program code, thereby storing them in a storage device for execution by a computing device, or fabricating them separately as individual integrated circuit modules, or fabricating multiple modules or steps into a single integrated circuit module. Thus, this application is not limited to any particular combination of hardware and software.

[0082] It is understandable that the motion control module 8 in the shaping device can be configured to perform the above-described shaping steps.

[0083] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
