Description

Technical Field

[0001] This application relates to the field of distribution box testing technology, and in particular to a low-voltage integrated distribution box testing device. Background Technology

[0002] As the fundamental unit of a power distribution system, the low-voltage integrated distribution box not only supports and secures electrical components such as circuit breakers, but also isolates the external environment, shields against electromagnetic interference, and ensures operational and maintenance safety. To meet requirements for strength, assemblability, and economy, the distribution box body is typically manufactured by bending sheet metal parts and then welding them together to form an integral structure. Surface pretreatment and powder coating (electrostatic powder spraying) or painting are then applied to form a protective outer layer. In modern industrial production lines, sheet metal welding and powder coating are the mainstream processes, providing good surface protection and consistent appearance while ensuring production capacity and cost control. Therefore, they are widely used in the mass production and assembly of low-voltage distribution boxes.

[0003] In existing technologies, common measures to ensure the uniformity and adhesion of the powder coating include: surface degreasing, chemical pretreatment (phosphating, conversion treatment), multi-angle or rotary spraying fixtures, baking and curing, and manual / automatic inspection of visible defects. To ensure coating quality, inspection methods typically include visual inspection, coating adhesion testing, coating thickness gauges, and localized peeling / corrosion testing of critical areas. In some high-requirement applications, more comprehensive surface defect detection solutions are employed, such as workpiece disassembly inspection, grooving inspection, or automated inspection of visible surfaces using image inspection systems. To compensate for powder coating blind spots, manual spraying, sanding, and touch-up coating are also used in production practice for localized repairs.

[0004] While the aforementioned processes and inspection methods achieve satisfactory protection in most flat and visible areas, traditional inspection methods still have significant blind spots in complex geometric shapes such as deep recesses, narrow seams, and internal corners formed by bending and welding. Existing inspection methods cannot effectively identify problems in these hidden areas. During long-term use, even with excellent overall sealing performance, these insufficiently coated areas are still highly susceptible to corrosion, leading to rust from the inside out and ultimately affecting the lifespan and electrical safety of the entire distribution box. Furthermore, some production lines have attempted to introduce vision inspection systems combined with automatic recoating nozzles, using cameras to identify coating defects and perform localized repairs. However, the recoating process often generates a large amount of suspended powder, which easily adheres to the surface of the inspection lens or optical window, rapidly degrading image quality. During continuous production, powder or atomized particles gradually accumulate on the lens surface, causing blurred images, reduced recognition rates, and even complete system failure. Therefore, how to reliably detect hidden coating dead zones such as deep corners and narrow gaps, based on the structural characteristics of low-voltage integrated distribution boxes, has become a key technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] This application provides a low-voltage integrated distribution box testing device, which realizes automatic transportation, accurate and comprehensive testing and immediate repair of low-voltage integrated distribution boxes, and also significantly improves the protective coverage of concealed parts, extends the service life of the distribution box and improves the overall electrical safety.

[0006] The low-voltage integrated distribution box testing equipment provided in this application adopts the following technical solution:

[0007] A low-voltage integrated distribution box testing device, comprising:

[0008] A machine platform, on which a conveyor belt is mounted, and a controller is installed;

[0009] The displacement assembly includes a support frame, a sliding beam, and a lifting arm. The support frame is fixed on the machine base, the sliding beam is slidably mounted on the support frame, the sliding beam is supported on the conveyor belt through the support frame, a sliding seat is slidably mounted on the sliding beam, and the lifting arm is raised and lowered on the sliding seat.

[0010] The detection component includes a deflection plate, a deflection drive, and a vision detection component. The deflection plate is rotatably mounted on one end of the lifting arm near the machine platform. The deflection drive is mounted on the lifting arm and its output end is connected to the deflection plate. The vision detection component is mounted on the deflection plate and electrically connected to the controller. The deflection drive can drive the deflection plate to rotate at one end of the lifting arm.

[0011] The repair assembly includes a reservoir and a nozzle. The reservoir is fixed on the sliding base and is filled with anti-rust paint. An output pump is provided on one side of the reservoir and is electrically connected to the controller. The nozzle is mounted on the deflection plate and is connected to the output end of the output pump. The reservoir is connected to the input end of the output pump.

[0012] By adopting the above technical solution, and by setting up displacement components including a support frame, sliding beam, and lifting arm, the detection and repair components can move and be positioned flexibly in three-dimensional space, thereby ensuring comprehensive coverage of the distribution box surface and its complex parts such as inner corners and welds. A deflectable plate with a visual inspection component is installed at the end of the lifting arm, enabling imaging inspection of the visible surface of the distribution box and multi-angle observation with the rotation of the deflector plate. This effectively overcomes the blind spots in deep recesses and narrow gaps that exist in traditional detection methods. Simultaneously, the integrated nozzle on the deflector plate forms an integrated structure between the detection and repair components, allowing for immediate targeted repair after detecting coating defects. This avoids the separate processes of "detection first, then manual repair" in traditional processes, improving the continuity and efficiency of detection and repair. Furthermore, it achieves automatic transport, accurate detection, and immediate repair of low-voltage integrated distribution boxes, significantly improving the protective coverage of concealed parts, extending the service life of the distribution box, and enhancing overall electrical safety.

[0013] Optionally, the visual inspection component is configured as an industrial endoscope. An isolating component is provided on the lens end of the visual inspection component. The isolating component includes a rotation drive, a rotating disk, a fixed disk, and an isolation plate. A sleeve is fixedly fitted onto the lens end of the visual inspection component. The fixed disk is fixedly mounted on the end of the sleeve facing away from the visual inspection component. A receiving groove is formed on the sleeve. The rotating disk is rotatably disposed within the receiving groove. The fixed disk is located above the rotating disk. A limiting groove is formed through the rotating disk. A limiting groove is fixed on one side of the isolation plate. A limiting rod is slidably disposed within the limiting groove. A limiting block is fixedly disposed on the side of the isolation plate opposite to the limiting rod. A guide groove is provided on the fixed disk, and the limiting block is slidably disposed within the guide groove. Multiple sets of isolation plates are provided, and the multiple sets of isolation plates are circumferentially distributed with the rotating disk as the center. Multiple sets of guide grooves are also provided. Driving the rotating disk to rotate can cause the isolation plates to slide along the length direction of the guide groove, thereby causing the isolation plates to move closer together to shield and protect the lens end of the vision inspection device.

[0014] By adopting the above technical solution, the visual inspection component is configured as an industrial endoscope, and an isolation structure consisting of a rotating drive, a rotating disk, a fixed disk, and isolation plates is added to its lens end. This provides effective physical protection for the lens end during inspection. When the rotating disk rotates under the drive, multiple sets of isolation plates distributed on its circumference slide along the guide grooves on the fixed disk, thereby closing each other to block and seal the lens end. This design, on the one hand, prevents paint splashes, dust impurities, or corrosive substances from directly adhering to the lens end, preventing the inspection image from becoming blurred due to contamination and ensuring the clarity and accuracy of the inspection results. On the other hand, the retractable structure of the isolation plates allows the lens to be in an open state when inspection is needed, and to be quickly closed for protection when not in use or in harsh environments, thus balancing inspection flexibility and equipment durability. Therefore, this not only improves the applicability and reliability of the inspection device in powder coating environments but also extends the service life of the visual inspection component and reduces maintenance costs.

[0015] Optionally, the rotation drive includes an electric drive module, a drive gear, and a driven gear. The electric drive module is disposed on the sleeve portion and is electrically connected to the controller. The electric drive module is provided with an output end. The drive gear is fixed on the output end of the electric drive module, and the driven gear is fixedly sleeved on the rotating disk. The drive gear meshes with the driven gear.

[0016] By adopting the above technical solution, the electric drive module can automatically drive the isolation plate, improve the flexibility and reliability of the lens protection structure, reduce manual adjustments, and ensure the automation and stability of the testing process.

[0017] Optionally, the fixed plate has a placement groove, a sponge block is placed in the placement groove, the sponge block is impregnated with epoxy paint remover, and the sponge block slides against the side of the isolation plate opposite to the visual inspection component.

[0018] By adopting the above technical solution, a placement groove is opened on the fixed plate, and a sponge block impregnated with epoxy paint remover is placed in it. This allows the isolation plate to continuously contact and rub against the sponge block as it slides with the rotating plate, thereby achieving automatic cleaning and paint removal of the isolation plate surface. This not only removes paint mist, dust, or impurities that may adhere to the isolation plate due to long-term use in a timely manner, preventing the accumulation on the isolation plate surface from causing obstruction of opening and closing, but also prevents the isolation plate from bringing contaminants to the lens end of the vision inspection component, ensuring the cleanliness and reliability of lens protection.

[0019] Optionally, the deflection plate is provided with an angle adjusting component for adjusting the position of the nozzle. The angle adjusting component includes an adjusting motor, a worm gear, and a turbine. A sliding groove is formed on the deflection plate, and the nozzle is slidably disposed in the sliding groove. The turbine is rotatably disposed on the deflection plate, and a connecting rod is provided between the turbine and the nozzle. The nozzle is connected to the turbine through the connecting rod. The worm gear is rotatably disposed on the deflection plate, and the adjusting motor is fixed on the deflection plate. One end of the worm gear is fixedly connected to the output end of the adjusting motor. The turbine meshes with the worm gear, and the turbine can drive the nozzle to reciprocate within the sliding groove.

[0020] By adopting the above technical solution, an angle adjustment component is installed on the deflection plate, and an adjustment motor drives the worm gear and worm wheel to change the position of the nozzle on the deflection plate. This allows for flexible adjustment of the nozzle's spray angle and position, ensuring precise control of the nozzle's spray direction and accurate coverage of the defect areas detected by the inspection components. Furthermore, it allows for flexible adaptation to the geometry and defect locations of different distribution boxes, avoiding spray dead zones caused by a fixed nozzle. Simultaneously, the worm gear transmission has self-locking properties, maintaining stability after the nozzle is adjusted to a specified angle, preventing displacement due to vibration or external forces, thus improving the accuracy and reliability of the repair process. Therefore, this design effectively enhances the nozzle's flexibility and adaptability, making the inspection and repair process more efficient and precise, and ensuring the protective integrity of the low-voltage integrated distribution box in complex structural areas.

[0021] Optionally, an abutment plate is fixedly provided on the deflection plate. The abutment plate is located on one side of the sliding groove. An abutment part is fixedly provided on the side of the abutment plate facing the sliding groove. The abutment part is in movable contact with the nozzle. When the abutment part contacts the nozzle, the nozzle will deflect to one side.

[0022] By adopting the above technical solution, the contact plate achieves passive fine-tuning of the nozzle angle through mechanical limiting. This not only reduces the reliance on complex electronic control and simplifies the control logic, but also expands the spraying angle range of the nozzle to a certain extent, allowing the repair liquid to cover more hidden areas and further enhancing the comprehensiveness and flexibility of the repair.

[0023] Optionally, a connecting pipe is fixedly provided on the output end of the output pump, and a connecting seat is fixedly provided at the end of the connecting pipe away from the output pump. The connecting seat is slidably disposed in the sliding groove. A ball-shaped connecting part is provided at one end of the nozzle. The connecting part is ball-hinged with the connecting seat, and the nozzle is in communication with the connecting pipe.

[0024] By adopting the above technical solution, the nozzle and the connecting seat are connected by a ball joint, which makes the nozzle more flexible. With the help of the abutment plate, it can automatically adjust the spray direction according to the complex geometry of the distribution box and the location of different defects. This ensures that the repair fluid can cover hidden areas that are difficult to reach by traditional spraying, such as deep recesses, narrow gaps and welds. It realizes the flexible adjustment of the nozzle during the repair process and further enhances the comprehensiveness and accuracy of the repair operation.

[0025] Optionally, the repair assembly further includes a return reed, which is sleeved on the nozzle. The return reed is configured as a flexible hollow tube with shape memory function. One end of the return reed is connected to the connecting seat, and the other end of the return reed is connected to the nozzle.

[0026] By adopting the above technical solutions, not only is it possible to prevent the nozzle from remaining in a non-working position due to prolonged deflection, ensuring that it can quickly return to the standard spraying position after completing the touch-up painting work, thus improving the continuity and stability of equipment operation; at the same time, the flexible hollow structure can absorb some mechanical impact or displacement error while ensuring the normal delivery of spraying liquid, reducing the risk of fatigue damage at the nozzle and pipeline interface, extending service life, effectively improving the nozzle's reset capability and safety in complex working environments, and further enhancing the practical value of the integrated testing and repair equipment.

[0027] Optionally, the deflection drive includes a deflection motor, a driving bevel gear, and a driven bevel gear. The deflection motor is fixedly mounted on one end of the lifting arm near the machine platform. A rotating seat is fixedly mounted on one end of the lifting arm near the machine platform. A deflection part is fixedly mounted on the deflection plate. A deflection shaft is fixedly mounted on the deflection part. The deflection part is rotatably mounted on the rotating seat via the deflection shaft. The output end of the deflection motor is connected to one end of the deflection shaft.

[0028] By adopting the above technical solutions, it is possible to achieve flexible deflection of the detection components and nozzles in three-dimensional space, expanding the observation angle of the visual inspection components and the repair coverage of the nozzles. It can also effectively overcome the blind spot problem in hidden areas such as deep recesses and narrow gaps in traditional single-direction or fixed-angle detection and spraying methods, and effectively improve the automation control level and reliability of the equipment.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. By setting up displacement components including a support frame, sliding beam, and lifting arm, the detection and repair components can move and be positioned flexibly in three-dimensional space, ensuring comprehensive coverage of the distribution box surface and its complex areas such as internal corners and welds. This not only enables imaging detection of the visible surfaces of the distribution box but also allows for multi-angle observation with the help of a rotating deflector plate, effectively overcoming the blind spots in deep recesses and narrow gaps inherent in traditional detection methods. Simultaneously, integrating a nozzle on the deflector plate creates an integrated structure between the detection and repair components, enabling immediate targeted repair after detecting coating defects. This avoids the separate processes of "detection first, then manual repair" in traditional processes, improving the continuity and efficiency of detection and repair. Furthermore, it achieves automatic transport, precise detection, and immediate repair of low-voltage integrated distribution boxes, significantly improving the protective coverage of concealed areas, extending the service life of the distribution box, and enhancing overall electrical safety.

[0031] 2. By configuring the visual inspection component as an industrial endoscope and adding an isolation structure to its lens end, effective physical protection can be provided for the lens end during the inspection process. This mechanism can prevent paint splashes, dust impurities, or corrosive substances from directly adhering to the lens end, preventing the inspection image from becoming blurred due to contamination and ensuring the clarity and accuracy of the inspection results. On the other hand, the retractable structure of the isolation plate allows the lens to be in an open state when inspection is needed, and can be quickly closed for protection when not in inspection or in harsh environments, thus balancing inspection flexibility and equipment durability. At the same time, a placement groove is opened on the fixed plate, and a sponge block impregnated with epoxy paint remover is placed in it. This allows the isolation plate to continuously contact and rub against the sponge block as it slides with the rotating plate, thereby achieving automatic cleaning and paint removal treatment of the isolation plate surface, preventing the accumulation on the isolation plate surface from obstructing opening and closing, and ensuring the cleanliness and reliability of lens protection.

[0032] 3. An angle adjustment component is installed on the deflection plate to change the position of the nozzle, thereby flexibly adjusting the spray angle and position of the nozzle. This not only ensures precise control of the nozzle's spray direction, allowing the sprayed liquid to accurately cover the defect areas detected by the detection components, but also allows for flexible adaptation to different electrical box geometries and defect locations, avoiding spray dead zones caused by a fixed nozzle. At the same time, the accompanying abutment plate enables passive fine-tuning of the nozzle angle, reducing reliance on complex electrical controls, simplifying the control logic, and expanding the spray angle range of the nozzle during the repair process to a certain extent. This allows the repair liquid to cover more hidden areas, further enhancing the comprehensiveness and flexibility of the repair. Attached Figure Description

One end of the connecting rod 444 is fixedly connected to the connecting seat 432, and the other end of the connecting rod 444 is fixedly connected to the turbine 443. The worm gear 442 is rotatably mounted on the deflection plate 31. The adjustment motor 441 is fixedly mounted on the deflection plate 31. One end of the worm gear 442 is fixedly connected to the output end of the adjustment motor 441. The turbine 443 meshes with the worm gear 442.

[0063] The position sensor is fixed on the deflection plate and is electrically connected to the controller 11. There are three sets of position sensors, which are respectively set on the two long sides and one wide side of the deflection plate 31.

[0064] A contact plate 45 is fixed on the deflection plate 31. The contact plate 45 is located on one side of the sliding groove 313. A contact part 451 is fixed on the side of the contact plate 45 facing the sliding groove 313. The contact part 451 is in contact with the nozzle 42. The side of the contact part 451 that contacts the nozzle 42 is set as an arc surface. Multiple sets of contact plates 45 are provided on the deflection plate 31. The multiple sets of contact plates 45 are evenly distributed at equal intervals along the length of the sliding groove 313. When the contact part 451 contacts the nozzle 42, the nozzle 42 will deflect to the side away from the visual inspection element 33.

[0065] The implementation principle of the low-voltage integrated distribution box testing equipment in this application embodiment is as follows: the distribution box to be tested is transported to the testing position by the conveyor belt on the machine base 1, the controller 11 starts the equipment, the linear motor drives the sliding beam 22 to move along the length direction of the machine base 1 to initially locate the testing area, the sliding drive component drives the sliding seat 221 to move along the length direction of the sliding beam 22, the lifting motor controls the lifting arm 23 to lift and lower through gear and rack transmission to adjust the testing height, the rotary motor drives the mounting base to rotate, thereby adjusting the horizontal angle of the testing component 3, and the displacement component 2 moves the visual inspection component 33 and the nozzle 42 to the top of the box to prepare for operation;

[0066] The deflection motor 321 drives the deflection plate 31 to deflect, adjusting the shooting angle of the vision inspection component 33. The vision inspection component 33 collects images of the inside of the box and transmits the data to the controller 11 in real time.

[0067] The controller 11 identifies defects through image processing algorithms. The core detection principle preset in the controller 11 is: detect first, then repair; detect from bottom to top, clockwise along the inner perimeter wall of the box, with special attention paid to complex areas (deep recesses, narrow gaps, inner corners).

[0068] When a defect is detected in the housing, the output pump 43 starts to draw epoxy zinc-rich anti-rust paint from the storage tank 41 and delivers it to the nozzle 42 through the delivery pipe and connecting pipe 431. The solenoid valve controls the flow of the paint, and the angle adjustment component 44 drives the connecting seat 432 to slide in the sliding groove 313, changing the position of the nozzle 42 on the deflection plate. The wedge-shaped part on the abutment plate 45 is passively mechanically linked with the nozzle 42. The nozzle 42 achieves further fine adjustment of the spraying angle through the ball joint structure and the return spring tube 46 to ensure that the paint is accurately sprayed to the defect.

[0069] If a defect is detected and repair is required, the rotating drive 341 drives the rotating disk 342 to rotate. The rotating disk 342 drives the six sets of isolation plates 344 to move closer to each other through the limiting groove 3421 and the guide groove 3431, blocking the lens end of the vision inspection component 33 to prevent paint from contaminating the lens during painting.

[0070] If no repair is needed or after repair is completed, the rotating disk 342 rotates in the opposite direction, the isolation plates 344 move away from each other and are stored in the receiving groove 3311. During the storage process, the sponge block 345 (containing epoxy paint remover) wipes the surface of the isolation plate 344 to prevent the paint from sticking together.

[0071] After a set of box inspections and repairs are completed, the spray nozzle 42 stops spraying, and the displacement component 2 drives the inspection component 3 and the repair component 4 away from the box area and resets to the initial position; the visual inspection component 33 can perform inspections again to confirm the repair effect, and the box moves out with the conveyor belt, and the next box enters, and the above process is repeated.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
