Technical Field
[0001] This invention relates to the field of medical device wiring technology, and in particular to a method for assembling a pathology scanner, an assembly device, and a pathology scanner. Background Technology
[0002] As a high-precision medical pathology testing device, the pathology scanner integrates multiple functional units such as an image acquisition module, motion control module, light source driving module, data transmission module, and power supply module. The signal transmission and power supply between the units are achieved through various cables, including high-speed differential signal cables, analog detection signal cables, digital control signal cables, high-power power cables, and low-voltage power supply cables.
[0003] The wiring design of existing pathology scanners often adopts an irregular and extensive layout, that is, cables are randomly placed according to the internal space of the equipment without systematic planning based on the high-precision detection requirements and electromagnetic compatibility requirements of the pathology scanner. This results in the internal cables of the pathology scanner being tangled and intertwined, and the cable types not matching the functional units. This makes the equipment susceptible to electromagnetic interference, affecting the detection accuracy. At the same time, the cables need to be repeatedly sorted during equipment debugging and troubleshooting, which greatly increases the maintenance workload. Summary of the Invention
[0004] To address the technical problem that current pathology scanner wiring designs suffer from tangled and intertwined cables, and mismatched cable types with functional units, making the equipment susceptible to electromagnetic interference and affecting detection accuracy, thus failing to meet the requirements for high precision and high reliability, this invention proposes a pathology scanner assembly method, assembly device, and pathology scanner.
[0005] To achieve the above objectives, the present invention proposes a method for assembling a pathology scanner. The pathology scanner includes a housing and multiple functional modules. The housing has an internal space for assembling the functional modules. The method for assembling the pathology scanner includes: The functional characteristics, signal transmission characteristics, and electromagnetic characteristics of the functional modules are obtained, and the internal space of the housing is functionally divided according to the functional characteristics and electromagnetic characteristics of the functional modules. Based on the signal transmission characteristics of the internal cables of the pathology scanner, the internal cables are classified. Based on the signal transmission characteristics of the functional modules, the classified cables are matched to each functional area; Plan the cabling path for each functional area, match the cables to each functional area according to the planned cabling path, and fix and isolate the cables for protection.
[0006] By adopting the above technical solution, the internal space of the pathology scanner is divided into multiple functional areas according to the functional characteristics of the functional modules. This fundamentally achieves physical spatial isolation between interference source components and sensitive source components, reducing electromagnetic radiation interference from strong interference source functional modules to highly sensitive imaging functional modules. Based on the signal transmission characteristics of each functional module, the classified cables are precisely matched to the corresponding functional areas to avoid cable type mismatch with functional modules, which could lead to strong electromagnetic radiation coupling to sensitive signal lines and thus affecting the detection accuracy of the equipment. The cabling paths of each functional area are planned to ensure that the cables of different functional areas are completely physically isolated and arranged in an orderly manner on the main trunk, fundamentally avoiding the tangling of multiple types of cables on the main trunk.
[0007] In the pathology scanner assembly method described above, the step of functionally dividing the internal space of the housing according to the functional characteristics and electromagnetic properties of the functional modules includes: Based on the functional characteristics of the functional modules, the internal space is divided into an image acquisition functional area, a data transmission functional area, a light source driving functional area, a power supply functional area, and a motion control functional area. Based on the electromagnetic characteristics of the internal components of the pathology scanner, the central region of the internal space is designated as the sensitive source region, the edge region of the internal space is designated as the strong interference source region, and the region between the sensitive source region and the strong interference source region is designated as the electromagnetic isolation transition region. Based on the electromagnetic characteristics of the functional modules, the image acquisition functional area and the data transmission functional area are arranged in the sensitive source area, the light source driving functional area and the power supply functional area are arranged in the strong interference source area, and the motion control functional area is arranged in the electromagnetic isolation transition area.
[0008] In the pathology scanner assembly method described above, the interval between each of the functional areas is ≥20mm.
[0009] The pathology scanner assembly method described above, wherein classifying the internal cables according to their signal transmission characteristics includes: Based on the signal transmission characteristics of the internal cables of the pathology scanner, the internal cables are divided into high-speed differential shielded cables, precision analog shielded cables, digital control cables, high-power power cables, low-voltage power cables, and grounding cables.
[0010] In the pathology scanner assembly method described above, the step of matching the classified cables to each functional area according to the signal transmission characteristics of the functional modules includes: The signal transmission characteristics of each functional module are matched with the signal transmission characteristics of various types of cables, and the cables corresponding to the signal transmission characteristics are matched to the corresponding functional areas based on the matching results.
[0011] In the pathology scanner assembly method described above, the wiring path planning for each functional area includes: Each functional area should have its own dedicated main cabling channel. Local path planning is carried out for the cables in each main cabling channel and the branch cables from each main cabling channel to each functional area; Reserve the cable length at the cable terminals in each functional area.
[0012] The pathology scanner assembly method described above, wherein the arrangement of independent main cabling channels for the cables of each functional area includes: The main cable routing channels located in the sensitive source area are arranged on the inside of the metal equipment frame, and the spacing between adjacent main cable routing channels is ≥30mm; The main cabling channel located in the strong interference source area is arranged on the outside of the metal equipment frame, and a metal partition is arranged between it and the main cabling channel in the sensitive source area for electromagnetic shielding. The main cabling channel located between the sensitive source area and the strong interference source area has a spacing of ≥20mm from the main cabling channels on both sides.
[0013] The pathology scanner assembly method described above, wherein local path planning is performed on the cables within each main cabling channel and the branch cables from each main cabling channel to each functional area, includes: Bundle cables of the same type within the same main cabling channel; For branch cables from the main cabling channel to the functional area, the path with the shortest straight distance and ≤2 corners should be selected, and the corners should be rounded. The minimum distance between all cable paths in the main cabling channel and the moving parts of the equipment must be ≥50mm.
[0014] Furthermore, to achieve the above objectives, the present invention also proposes a pathology scanner assembly apparatus, which includes: a memory, a processor, and a pathology scanner assembly program stored in the memory and executable on the processor, wherein the pathology scanner assembly program is configured to implement the pathology scanner assembly method as described above.
[0015] In addition, to achieve the above objectives, the present invention also proposes a pathological scanner, which is manufactured using the pathological scanner assembly method described above.
[0016] Compared with the prior art, the pathology scanner assembly method, assembly device, and pathology scanner proposed in this invention have the following beneficial effects: 1. The pathology scanner assembly method proposed in this invention arranges the internal space of the pathology scanner into zones according to the degree of electromagnetic interference, classifies the cables and matches them with the functional zones, and fundamentally isolates the interference source components from the sensitive source components, reducing the electromagnetic radiation interference of the strong interference source functional module to the highly sensitive imaging functional module. Furthermore, the wiring path planning of the cables in each functional area ensures that the cables in different functional areas are completely physically isolated and arranged in an orderly manner on the main trunk line, fundamentally avoiding the tangling of multiple types of cables on the main trunk section.

Detailed Implementation
[0019] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0020] The wiring design of existing pathology scanners often adopts an irregular and extensive layout, that is, cables are randomly placed according to the internal space of the equipment without systematic planning based on the high-precision detection requirements and electromagnetic compatibility requirements of the pathology scanner. This results in the internal cables of the pathology scanner being tangled and intertwined, and the cable types not matching the functional units. This makes the equipment susceptible to electromagnetic interference, affecting the detection accuracy. At the same time, the cables need to be repeatedly sorted during equipment debugging and troubleshooting, which greatly increases the maintenance workload.
[0021] To address the aforementioned technical problems, this invention proposes a solution: First, the functional characteristics, signal transmission characteristics, and electromagnetic characteristics of the functional modules are obtained, and the internal space of the housing is functionally divided according to these characteristics. Then, the internal cables are classified according to their signal transmission characteristics. Next, the classified cables are matched to each functional area according to the signal transmission characteristics of the functional modules. Finally, wiring paths are planned for each functional area, and the cables matched to each functional area are routed according to the planned wiring paths, with the cables then fixed and isolated for protection.
[0022] The above scheme divides the internal space of the pathology scanner into multiple functional areas based on the functional characteristics of the modules. This fundamentally isolates interference-generating components from sensitive components, reducing electromagnetic radiation interference from strong interference-generating modules to highly sensitive imaging modules. Based on the signal transmission characteristics of each functional module, the categorized cables are precisely matched to their corresponding functional areas, preventing cable type mismatches from coupling strong electromagnetic radiation to sensitive signal lines and affecting the equipment's detection accuracy. Furthermore, cable routing planning for each functional area ensures complete physical isolation and orderly arrangement of cables along the main trunk, fundamentally preventing multiple types of cables from intertwining and tangling on the main trunk.
[0023] Based on the above, please refer to Figure 1 As shown in the embodiments of this specification, a method for assembling a pathology scanner is proposed. The pathology scanner includes a housing and multiple functional modules. The housing has an internal space for assembling the functional modules. The method for assembling the pathology scanner includes steps S10-S40, wherein: S10, acquire the functional characteristics, signal transmission characteristics and electromagnetic characteristics of the functional module, and divide the internal space of the housing into functional categories based on the functional characteristics and electromagnetic characteristics of the functional module.
[0024] The functional characteristics of a functional module refer to its inherent physical properties, working principles, and performance indicators. These characteristics include, but are not limited to, electrical operating parameters, physical installation parameters, and mechanical characteristic parameters. The signal transmission characteristics of a functional module refer to the electrical characteristics, transmission capabilities, and quality requirements of the electrical signals transmitted between functional modules. These characteristics include, but are not limited to, signal type, signal transmission rate, and signal level. The electromagnetic characteristics of a functional module refer to its ability to generate electromagnetic interference in an electromagnetic environment and its ability to resist external electromagnetic interference. These characteristics include, but are not limited to, electromagnetic emission characteristics and electromagnetic sensitivity.
[0025] In its implementation, the pathology scanner integrates multiple functional modules, such as an image acquisition module, motion control module, light source driving module, data transmission module, and power supply module. Based on the working characteristics of these modules, the internal space is divided into multiple functional areas, which are further partitioned according to the electromagnetic characteristics of the internal components. This achieves physical spatial isolation between the interference source devices and the sensitive source devices at the source of electromagnetic interference, significantly reducing the electromagnetic radiation interference from strong interference source modules to highly sensitive imaging modules. This significantly improves the overall anti-interference capability of the pathology scanner and ensures the stability and accuracy of image acquisition and signal transmission.
[0026] In addition, dividing different functional areas into separate wiring zones with clear electromagnetic environment boundaries in physical space avoids cross-zone wiring of cables with different electromagnetic characteristics, and avoids serious electromagnetic interference during subsequent wiring, which would lead to noise in image acquisition and reduced motion control precision, thereby affecting the imaging quality and accuracy of pathological slide scanning.
[0027] S20 classifies the internal cables based on their signal transmission characteristics.
[0028] In practical implementation, based on the signal transmission characteristics of the internal cables of the pathology scanner, the internal cables are classified into high-speed differential shielded cables, precision analog shielded cables, digital control cables, high-power power cables, low-voltage power cables, and grounding cables. This allows for physical isolation of different types of cables or the adoption of protective measures corresponding to the interference characteristics of each type of cable when wiring various functional areas. This significantly improves the electromagnetic interference resistance of the pathology equipment and enhances the standardization, maintainability, and reliability of the equipment wiring.
[0029] S30, according to the signal transmission characteristics of the functional modules, match the classified cables to each functional area.
[0030] In practice, based on the signal transmission characteristics of each functional area, the classified internal cables are precisely matched with the corresponding functional areas. This physically separates cables with strong interference sources (such as power cables) from cables with sensitive signals (such as image data transmission cables and sensor signal cables), reducing electromagnetic coupling and crosstalk between cables from the source and improving the imaging accuracy and detection results of the pathology scanner.
[0031] Secondly, each functional area is precisely matched with the required cable type to avoid the situation of cable type mismatch with functional module, which is the same as the traditional irregular and extensive wiring. For example, using ordinary cable to transmit high-speed differential signal will lead to signal attenuation and reduced transmission rate, or using high-end shielded cable to transmit low-voltage DC power will increase material cost.
[0032] S40 plans the cabling path for each functional area, matches the cables to each functional area according to the cabling path plan, and fixes and isolates the cables for protection.
[0033] In practical implementation, based on the metal frame of the pathology scanner and prefabricated cable trays / frames, independent main cable routing channels are arranged for the cables in each functional area. Each main cable routing channel corresponds to the cables required for a functional area, so that the cables of different functional areas are completely physically isolated and arranged in an orderly manner on the main cable, fundamentally avoiding the tangling of multiple types of cables on the main section. Secondly, the same type of cables in each main cable routing channel are bundled together with nylon cable ties to avoid the cables being scattered in the main cable routing channel, which would lead to electromagnetic interference and space occupation. For the branch cables from the main cable routing channel to the functional area, that is, the branch path from the main cable routing channel to the module terminal, the path with the shortest straight line and the fewest corners is selected, and the corners are rounded to avoid the cable shielding layer being damaged by right angles, which would lead to signal attenuation.
[0034] Secondly, the cables are isolated and protected to further enhance their resistance to mechanical damage and electromagnetic interference. This is especially effective for cables that pass through metal plate holes, are near sharp edges, or pass through high or low temperature areas, preventing cutting, squeezing, and thermal aging.
[0035] Alternatively, please refer to Figure 2 As shown, in step S10, the internal space of the housing is functionally divided according to the functional characteristics and electromagnetic characteristics of the functional modules, and steps S11-S14 are also included, wherein: S11, based on the working characteristics of the functional modules, the internal space is divided into an image acquisition functional area, a data transmission functional area, a light source driving functional area, a power supply functional area, and a motion control functional area; S12, based on the electromagnetic characteristics of the internal components of the pathology scanner, the central region of the internal space is set as the sensitive source region, the edge region of the internal space is set as the strong interference source region, and the region between the sensitive source region and the strong interference source region is set as the electromagnetic isolation transition region. S13, based on the electromagnetic characteristics of the functional modules, the image acquisition functional area and the data transmission functional area are arranged in the sensitive source area, the light source driving functional area and the power supply functional area are arranged in the strong interference source area, and the motion control functional area is arranged in the electromagnetic isolation transition area.
[0036] Specifically, based on the working principle of the pathology scanner and according to the working characteristics of its integrated functional modules, the internal space is divided into an image acquisition functional area, a data transmission functional area, a light source driving functional area, a power supply functional area, and a motion control functional area. Each functional area corresponds to a functional module. Due to the different electromagnetic characteristics of the internal components of the pathology scanner, in order to achieve basic electromagnetic shielding for each functional area, based on the spatial attenuation law of electromagnetic radiation (electromagnetic radiation intensity is inversely proportional to the square of the distance) and the shell shielding effect, sensitive source devices susceptible to electromagnetic interference (such as control chips, image sensors, Ethernet modules, etc.) are arranged in the central area of the internal space, and this area is designated as the sensitive source area. Interference source devices prone to electromagnetic radiation or transmission interference (such as switching power supplies, LED lights, etc.) are placed in the central area. The source, conversion module, etc. are arranged in the edge area of the internal space, which is designated as the strong interference source area. The area between the sensitive source area and the strong interference source area is designated as the electromagnetic isolation transition area. Then, the image acquisition function area and data transmission function area with the highest electromagnetic sensitivity are arranged in the central sensitive source area, keeping them away from all strong interference sources to obtain the best electromagnetic protection. The light source driving function area and power supply function area, which are prone to electromagnetic interference, are arranged in the strong interference source area, away from the sensitive source area. The shell shielding effect is used to limit their interference to a local area, and grounding is used for rapid discharge. The motion control function area, which is less susceptible to electromagnetic interference, is arranged in the electromagnetic isolation transition area, which avoids direct interference to the central sensitive area and prevents the edge strong interference sources from affecting its encoder and other sensitive devices.
[0037] It should be noted that the aforementioned image acquisition functional area is the installation area for the image acquisition functional module. This area primarily transmits high-speed differential image signals and analog photosensitive signals, exhibiting signal transmission characteristics of small signal amplitude and susceptibility to electromagnetic interference. The aforementioned motion control functional area is the installation area for the motion control functional module. This area primarily transmits digital control signals, motor drive pulse signals, and low-voltage power supply signals, exhibiting signal transmission characteristics susceptible to low- and medium-frequency switching interference. The aforementioned light source drive functional area is the installation area for the light source drive functional module. This area primarily transmits high-power power supply signals and brightness adjustment analog signals, exhibiting signal transmission characteristics susceptible to strong electromagnetic radiation and conducted interference. The aforementioned data transmission functional area is the installation area for the data transmission functional module. This area primarily transmits high-speed Ethernet signals and USB high-speed data signals, exhibiting signal transmission characteristics of high transmission rate and easy signal attenuation. The aforementioned power supply functional area is the installation area for the power supply functional module. This area primarily transmits 220V AC power and various DC high-voltage / low-voltage power supplies, exhibiting signal transmission characteristics susceptible to strong power frequency interference and switching power supply interference.
[0038] It should also be noted that the mounting bases for installing functional modules in each functional area are made of metal to achieve basic electromagnetic shielding for each functional area.
[0039] It is worth noting that the spacing between the above-mentioned functional areas is ≥20mm, so as to reserve physical isolation space between the functional areas and avoid electromagnetic coupling between them.
[0040] In this embodiment, during the scanning process, the image acquisition and data transmission functional areas of the pathology scanner are extremely sensitive to electromagnetic interference. Even slight noise can be superimposed on the image signal, causing noise and stripes in the image. Therefore, the sensitive source area needs to be located in the central area of the internal space. Taking advantage of the relatively stable characteristics of the central area of the device, with small temperature fluctuations and minimal vibration effects, an optimal electromagnetic shielding environment can be obtained. Since the light source driving circuit of the light source driving functional area generates high-frequency switching noise, and the power supply circuit of the power supply functional area generates strong electromagnetic radiation, which strongly interferes with the imaging quality and detection accuracy of the pathology scanner, they need to be located in the edge area of the internal space to avoid strong interference to the functional modules of the sensitive source area, thus affecting the imaging quality and detection accuracy of the pathology scanner. At the same time, the edge area can independently shield and filter the cables of the strong interference source area to prevent interference signals from coupling into the interior through the wiring harness. The motion control functional area is arranged between the sensitive source area and the strong interference source area as an electromagnetic isolation transition area, which can weaken the interference signal propagating from the strong interference source area to the sensitive source area, ensuring the imaging quality and detection accuracy of the pathology scanner.
[0041] Alternatively, please refer to Figure 3 As shown, in step S20, the internal cables of the pathology scanner are classified according to their signal transmission characteristics. The process also includes step S21, wherein: S21, based on the signal transmission characteristics of the internal cables of the pathology scanner, divides the internal cables into high-speed differential shielded cables, precision analog shielded cables, digital control cables, high-power power cables, low-voltage power cables, and grounding cables.
[0042] It should be noted that the above-mentioned high-speed differential shielded cable uses a silver-plated copper core with an outer aluminum foil shield and a braided mesh double-layer shielding structure, mainly used for transmitting high-speed differential image signals and Ethernet high-speed signals; the above-mentioned precision analog shielded cable uses an oxygen-free copper core with an outer aluminum foil shielding single-core shielding structure, wherein the core insulation layer is preferably made of low-loss polytetrafluoroethylene, mainly used for transmitting analog photosensitive signals of image sensors and analog signals for adjusting the brightness of light sources; the above-mentioned digital control cable uses an oxygen-free copper core with an unshielded twisted-pair structure, mainly used for transmitting stepper motor control signals and digital control signals between various functional modules; the above-mentioned high-power power cable uses an oxygen-free copper core with a single-core / multi-core unshielded structure, mainly used for transmitting high-voltage power supplies for light source drives and high-power power supplies for motors; the above-mentioned low-voltage power supply cable uses an oxygen-free copper core with a multi-core unshielded structure, mainly used for transmitting low-voltage DC power supplies (such as 5V / 12V / 24V, etc.) to various functional modules; the above-mentioned grounding cable uses a tin-plated copper core, mainly used for grounding various functional areas, equipment housings, or shielding layers.
[0043] In this embodiment, the internal cables are classified into high-speed differential shielded cables, precision analog shielded cables, digital control cables, high-power power cables, low-voltage power cables, and grounding cables. This allows for physical isolation of different types of cables or the adoption of protective measures corresponding to the interference characteristics of each type of cable when wiring various functional areas. This significantly improves the electromagnetic interference resistance of the pathology equipment and enhances the standardization, maintainability, and reliability of the equipment wiring.
[0044] Alternatively, please refer to Figure 4 As shown, in step S30, the classified cables are matched to each functional area according to the signal transmission characteristics of the functional modules. The process also includes step S31, wherein: S31, the signal transmission characteristics of the functional module are matched with the signal transmission characteristics of various types of cables respectively, and according to the matching results, the cables corresponding to the signal transmission characteristics are matched to the corresponding functional areas.
[0045] Specifically, since each type of cable has different applicable scenarios and different signal transmission characteristics, the signal characteristics of each type of cable are matched with the signal transmission characteristics of each functional area, and the corresponding cable is matched to the corresponding functional area. For example, the high-speed differential shielded cable mentioned above is mainly used to transmit high-speed differential image signals and Ethernet high-speed signals, while the image acquisition functional area mainly transmits high-speed differential image signals and analog photosensitive signals, which corresponds to the signal transmission characteristics of the high-speed differential shielded cable. Therefore, the image acquisition functional area is matched with the high-speed differential shielded cable.
[0046] It should be noted that the specific matching results of each functional area and cable type are as follows: the above image acquisition functional area matches the high-speed differential shielded cable and the precision analog shielded cable; the above motion control functional area matches the digital control cable, the high-power power cable and the low-voltage power supply cable; the above light source driving functional area matches the high-power power cable and the precision shielded cable; the above data transmission functional area matches the high-speed differential shielded cable; and the above power supply functional area matches the high-power power cable, the low-voltage power supply cable and the grounding cable.
[0047] It is worth noting that after matching the above-mentioned functional areas with various types of cables, it is necessary to further verify whether the current carrying capacity, characteristic impedance, and shielding characteristics of the cables are consistent with the signal transmission / power transmission requirements of the corresponding functional areas. This is to avoid problems such as signal attenuation, power overload, and increased electromagnetic interference caused by cable mismatch, which could affect the imaging quality and detection accuracy of the pathology scanner.
[0048] In this embodiment, each functional area is precisely matched with the required cable type to avoid situations where the cable type does not match the functional module. This prevents image signal degradation caused by using ordinary cables in sensitive source areas, and also prevents safety hazards caused by insufficient current carrying capacity of power transmission cables. Furthermore, it avoids crosstalk and coupling caused by electromagnetic incompatibility between different types of cables in mixed wiring, thereby improving the working reliability of the pathology scanner equipment and significantly shortening the product development and production debugging cycle.
[0049] Alternatively, please refer to Figure 5 As shown, in step S40, the wiring path planning for each functional area also includes steps S41-S43, wherein: S41, each functional area has an independent main cabling channel; S42, perform local path planning for the cables in each main cabling channel and the branch cables from each main cabling channel to each functional area; S43, reserve cable length at the cable terminals in each functional area.
[0050] In step S43, the cable terminals are divided into fixed installation terminals, removable maintenance terminals, and special module terminals according to the installation method and terminal type of each module in the functional area.
[0051] It should be noted that the reserved cable length of the fixed installation terminal is 50±5mm, the reserved cable length of the detachable maintenance terminal is 150±10mm, and the reserved cable length of the special module terminal is the reserved cable length of the detachable maintenance terminal plus the travel distance plus 20mm.
[0052] In this embodiment, sufficient cable length is reserved at the cable connection end to provide ample operational margin for equipment assembly, debugging, maintenance, disassembly, and cable replacement. This avoids difficulties in plugging and unplugging due to excessively short cables, or loose terminals, poor contact, or even wire core breakage caused by forced pulling. Fixing the cable can prevent displacement, swinging, or friction with other components during equipment transportation or scanning operations, thus avoiding the risk of cable insulation wear, short circuits, or detachment.
[0053] It should be noted that all the main cabling channels mentioned above are enclosed prefabricated cabling troughs, with the trough body made of metal to achieve electromagnetic shielding of the cables in the main cabling channel. For signal cables and power cables that exist in the same functional area, a partition plate is also installed in the trough to divide the main cabling channel into a signal cable area and a power cable area, so as to achieve secondary electromagnetic isolation of signal cables and power cables in the same functional area.
[0054] It should also be noted that the routing paths of high-speed shielded cables and precision analog shielded cables must be free from twisting and compression to ensure the integrity of the shielding layer and avoid sudden changes in characteristic impedance caused by cable compression and deformation, which would affect the transmission of image signals. The routing paths of high-power power cables must be free from overlapping and entanglement to avoid increased heat generation and electromagnetic interference caused by overlap. The routing paths of grounding cables should use the shortest straight path without corners or redundancy, while ensuring that the grounding resistance is ≤0.1Ω to achieve effective grounding.
[0055] It is worth noting that the height of the aforementioned partition plate must be ≥50mm; and the minimum distance between the routing path of all cables and the metal sharp corners or edges of the equipment must be ≥20mm.
[0056] In this embodiment, all cable routing paths must be kept away from the metal sharp corners or edges of the equipment, ensuring a minimum distance of ≥20mm from the metal sharp corners or edges of the equipment. The purpose is to avoid corona discharge generated by the metal sharp corners or edges of the equipment from interfering with the cable signals.
[0057] Alternatively, please refer to Figure 6As shown, in step S41, which arranges independent main cabling channels for the cables of each functional area, steps S411-S413 are also included, wherein: S411, the main cable routing channel located in the sensitive source area is arranged on the inside of the metal equipment frame, and the spacing between adjacent main cable routing channels is ≥30mm; S412, the main cabling channel located in the strong interference source area is arranged on the outside of the metal equipment frame, and a metal partition is arranged between it and the main cabling channel in the sensitive source area for electromagnetic shielding. S413 is the main cabling channel located between the sensitive source area and the strong interference source area, with a spacing of ≥20mm between it and the main cabling channels on both sides.
[0058] It should be noted that the metal partition installed between the sensitive source area and the strong interference source area must be ≥0.5mm thick, and the metal partition and the equipment casing must be reliably grounded.
[0059] The metal partition includes, but is not limited to, sheet metal and aluminum plate. In this embodiment, due to the excellent conductivity and grounding performance of the equipment's metal frame, the main wiring channels of the sensitive source area are arranged inside the metal frame. This allows the metal frame to isolate electromagnetic interference from external or edge strong interference source areas. Simultaneously, the spacing between adjacent main wiring channels in the sensitive source area is ≥30mm, providing physical isolation and reducing electromagnetic crosstalk between wiring harnesses caused by close parallel operation. The main wiring channels of the strong interference source area are arranged outside the metal frame, with a metal partition added between them, forming a double-layer shielding structure. This significantly reflects and absorbs electromagnetic interference generated by the strong interference source area, greatly reducing the coupling interference of power lines to signal lines and improving the imaging accuracy and detection results of the pathology scanner. The main wiring channel of the motion control functional area, located between the sensitive source area and the strong interference source area, serves as a transition and buffer.
[0060] Alternatively, please refer to Figure 7 As shown, in step S42, local path planning is performed on the cables in each main cabling channel and the branch cables from each main cabling channel to each functional area. This also includes steps S421-S423, where: S421, bundle and route cables of the same type within the same main cabling channel; S422, for the branch cable paths from the main cabling channel to the functional area, select the path with the shortest straight distance and ≤2 corners, and use rounded transitions at the corners; S423, the minimum distance between all cable paths in the main cabling channel and the moving parts of the equipment must be ≥50mm.
[0061] When bundling cables of the same type within the same main cabling channel, nylon cable ties are used to bundle the cables of the same type into one or more bundles. It is worth noting that the spacing between different bundles is ≤150mm, and the spacing between individual bundles is ≤30mm.
[0062] It should be noted that when the above-mentioned cables use a rounded transition at corners, the radius of curvature must be ≥50mm to avoid damage to the cable shielding layer and signal attenuation caused by right-angle corners.
[0063] It should also be noted that for local wiring in sensitive source areas, all cables must be routed along the metal mounting base to achieve electromagnetic shielding, and cables must not be suspended in the air; for local wiring in areas with strong interference sources, the spacing between power cables and signal cables should be ≥10mm, and power cables should be placed below signal cables to prevent the radiation interference from power cables from being vertically coupled to signal cables.
[0064] In this embodiment, cables of the same type within the same main channel are bundled together. This avoids electromagnetic interference caused by scattered cables within the main channel and reduces cable tangling, resulting in a neat and orderly main channel that facilitates heat dissipation, maintenance, and reduces space occupancy. For branch cable paths from the main channel to functional areas, the shortest straight-line distance and the fewest corners are selected. This shortens the signal transmission path, reduces the attenuation of weak analog signals and the latency of high-speed digital signals, ensuring the real-time performance and accuracy of image acquisition and transmission. Rounded transitions are used at corners to avoid damage to the cable shielding layer caused by right-angle corners, which could lead to signal attenuation. All cables are kept at a distance from moving or heat dissipation components to prevent cables from being pulled or cut by moving parts, thus preventing short circuits or signal interruptions due to cable damage and improving the operational safety of the pathology scanner during long-term dynamic scanning.
[0065] Alternatively, please refer to Figure 8 As shown, in step S40, which involves fixing and isolating the cable along the wiring path, steps S44-S46 are also included, wherein: S44. All cables are secured with fasteners. The spacing between fasteners in the main cable routing channel is ≤30mm, and the spacing between fasteners in the branch paths is ≤150mm.
[0066] The fasteners include, but are not limited to, metal clips, nylon cable ties, and cable clamps. It should be noted that, when protecting cables as described above, both ends of the shielding layer of high-speed differential shielded cables and precision analog shielded cables are reliably grounded to the equipment casing to achieve full shielding protection.
[0067] In this embodiment, the cable is fixed in order to prevent the cable from shaking and causing poor contact at the terminal, which would affect the image signal quality and detection results.
[0068] S45, a fixing point must be installed 10mm from the root of all cable terminals.
[0069] In this embodiment, all cable terminals are equipped with fixing points, directing most of the external tensile and bending forces directly to these fixing points rather than the terminal crimping points. This prevents terminals from loosening due to accidental cable pulling and improves the long-term contact reliability between the cables and components. S46. Protective covers shall be placed over all cables where they come into contact with sharp metal corners or moving parts of the equipment.
[0070] The protective sleeve includes, but is not limited to, a rubber protective sleeve or a corrugated pipe sleeve.
[0071] In this embodiment, isolating and protecting the cable further enhances its resistance to mechanical damage and electromagnetic interference. In particular, for cables that pass through holes in metal plates, are near sharp edges, or pass through high or low temperature areas, it can effectively prevent cutting, squeezing, and thermal aging.
