Description

Technical Field

[0001] The invention relates to the technical field of electrical automation equipment detection, in particular to a detection device for electrical automation equipment. Background Art

[0002] With the rapid development of electrical automation technology, electrical automation equipment has been widely used in many key fields such as industrial production, intelligent buildings, and power systems. This trend has not only promoted the efficient operation of various industries, but also increased the output of electrical automation equipment. In this context, accurate and comprehensive testing of electrical automation equipment has become a core link to ensure equipment quality and improve production reliability.

[0003] At the front end of the testing process, equipment handling mostly relies on manual operation, and testing personnel need to expend a lot of physical strength to move the equipment to be tested to the testing area one by one. This method is inefficient and seriously slows down the overall testing rhythm. Especially when faced with the massive testing needs brought about by large-scale production, it becomes increasingly unable to cope with the requirements of rapid screening.

[0004] When it comes to the actual inspection stage, the traditional method often requires manual flipping of the equipment to check different parts of the equipment, especially the bottom, sides and other non-visual surfaces.

[0005] Since it is difficult to accurately control the force and flipping angle during manual operation, this is not only very likely to cause secondary damage to the equipment such as bumps and scratches, resulting in damage to the appearance of the equipment and displacement of internal precision components, but it is also impossible to ensure that the equipment is in a standardized testing position after each flip, which greatly reduces the detection accuracy and makes it difficult to maintain the accuracy and consistency of the test results.

[0006] In view of this, this application is hereby filed. Summary of the invention

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0022] See also Figure 1-8 , the present invention provides a technical solution: A detection device for electrical automation equipment includes a conveying device 1, a mounting plate 2 and a clamping plate 4. The conveying device 1 includes brackets on both sides and a conveyor belt in the middle. The conveying device 1 is provided with detection cameras. There are four detection cameras, which are respectively located at the two ends of both sides directly behind the mounting plate 2.

[0023] The electrical automation equipment is placed on the conveyor belt of the conveying device 1. The conveyor belt relies on the brackets on both sides to provide stable support and starts to operate under power drive to smoothly transport the electrical automation equipment to be tested toward the direction of the installation plate 2.

[0024] When the device is transported to a specific position, that is, close to the mounting plate 2, the clamping plate 4 starts to function to clamp and fix the device.

[0025] Through the mechanical structure design of the clamping plate 4, it can fit closely to both sides of the device, limit the displacement of the device in the subsequent detection process, and provide stable support conditions for accurate detection.

[0026] After the device is fixed by the clamping plate 4, four detection cameras located at both ends of both sides behind the mounting plate 2 are started synchronously.

[0027] These inspection cameras aim at the equipment from different angles to collect visual information such as the equipment's appearance and component assembly status. The camera then transmits the acquired image data to a matching analysis system. The system processes and identifies the image based on preset inspection standards to check whether the equipment has defects.

[0028] The combination of the conveying device 1 and the detection camera forms a semi-automatic detection process. The equipment can be continuously transported to the detection position without manual handling, which greatly saves manpower handling time and significantly improves the detection efficiency. It is suitable for rapid screening of large-scale electrical automation equipment.

[0029] Four inspection cameras are distributed at both ends of both sides directly behind the mounting plate 2. This multi-angle layout can cover multiple key visible surfaces of the equipment, avoid detection blind spots, and accurately capture subtle defects in different parts of the equipment, such as scratches on the outer casing, loose or missing parts, etc., to improve the comprehensiveness of detection.

[0030] The overall device structure is relatively simple and clear, and the conveying device 1, the clamping plate 4, and the detection camera have clear division of labor.

[0031] Operators can easily get started with the operation in daily use. No complicated training is required for placing the equipment, starting the inspection process, or subsequently removing the equipment, which reduces labor costs and operating thresholds.

[0032] The brackets on both sides of the conveying device 1 provide a solid support foundation for the conveyor belt, ensuring that the equipment moves forward smoothly during the conveying process and reducing shaking and bumps.

[0033] After being fixed by the clamping plate 4, the device can maintain a stable posture during detection, avoiding deviation of the detection result due to device shaking, and ensuring the accuracy of the detection result.

[0034] A movable sheet 401 is arranged on the inner side of the splint 4, and a plurality of movable sheets 401 are arranged in a circular array. A sliding sleeve 404 is arranged on the outer side of the movable sheet 401, and a fixed sleeve 403 is arranged on the outer side of the sliding sleeve 404. The sliding sleeve 404 is hollow, and a clamping spring 405 is arranged in the sliding sleeve 404. The other ends of the fixed sleeve 403 and the clamping spring 405 are fixedly connected to the splint 4.

[0035] When the electrical automation equipment needs to be clamped, the clamping plate 4 moves closer to the equipment. As the clamping plate 4 gradually approaches the equipment, the movable sheet 401 first contacts the housing of the equipment.

[0036] Due to the different shapes of different devices, there may be convex structures on the shell surface, and the movable piece 401 is squeezed by the device shell and begins to move outward. The movable piece 401 drives the sliding sleeve 404 connected thereto to slide outward along the fixed sleeve 403. During this process, the clamping spring 405 inside the sliding sleeve 404 is compressed.

[0037] Relying on the elastic deformation of the clamping spring 405, the spring generates a reverse force to continuously push the sliding sleeve 404 and the movable sheet 401, so that the movable sheet 401 always fits tightly against the outer shell surface of the device.

[0038] Regardless of whether the device housing is a regular square, round, or has irregular protrusions, the multiple movable pieces 401 distributed in a circular array can flexibly adjust their positions according to the contour of the housing to achieve a tight and stable clamping effect.

[0039] The conventional clamping plate 4 is usually a rigid structure, which is difficult to handle electrical automation equipment with complex shapes and protrusions on the surface.

[0040] The design of the clamping plate 4 with the circular array movable plates 401 can adapt to the shapes of different devices, greatly expanding the application range of the detection device. It can handle a variety of electrical equipment without the need to customize a dedicated clamping plate 4 for each specific shape of the device.

[0041] The movable sheet 401 is in a flexible and fitting manner when in contact with the device housing and adaptively adjusting its position.

[0042] Compared with the possible scratches and extrusion damages caused by the rigid clamping plate 4, this design effectively avoids damage to the paint surface and delicate parts of the equipment casing, especially for some high-precision and high-value electrical automation equipment, reducing the risk of damage due to clamping during the detection process.

[0043] The clamping spring 405 provides a continuous and stable clamping force for the movable sheet 401 .

[0044] Even if the device is disturbed by slight vibration, shaking or other external forces during the detection process, the spring force can compensate in time to maintain the close contact between the movable sheet 401 and the device casing, ensuring that the device is firmly fixed in the detection position, avoiding displacement affecting the detection accuracy, and creating favorable conditions for subsequent precise detection.

[0045] Since there is no need to frequently replace the clamping plate 4 adapted to devices of different shapes, the operator can quickly place the device on the conveying device 1 and quickly complete the clamping positioning, which reduces the equipment preparation time, makes the entire detection process smoother, and indirectly improves the detection efficiency of the detection device for a large number of different electrical equipment.

[0046] Furthermore, a raising frame 201 is provided on the top surface of the mounting plate 2, and a motor 202 is installed on the raising frame 201. A limiting plate 203 is provided at the end of the mounting plate 2 near the conveying device 1, and a limiting protrusion 204 is provided on the limiting plate 203. The output shaft of the motor 202 is connected to a screw rod 205, and the outer side of the screw rod 205 is threadedly connected to a screw sleeve 206, and the outer side of the screw sleeve 206 is provided with a limiting groove 207 adapted to the limiting protrusion 204.

[0047] When it is necessary to drive the relevant components to move, the motor 202 installed on the raising frame 201 is started, and the output shaft of the motor 202 drives the screw 205 to rotate.

[0048] The screw 205 serves as a transmission element and forms a spiral transmission structure with the outer screw sleeve 206. Due to the threaded connection, the rotational motion of the screw 205 is converted into the linear motion of the screw sleeve 206.

[0049] A limiting groove 207 adapted to the limiting protrusion 204 on the limiting plate 203 is provided on the outer side of the screw sleeve 206. When the screw sleeve 206 moves axially along the screw rod 205, the limiting protrusion 204 is inserted into the limiting groove 207, playing a dual role of guiding and limiting.

[0050] Furthermore, the back side of the splint 4 is connected to the telescopic column 3, a telescopic groove 302 adapted to the telescopic column 3 is opened in the screw rod 205, a telescopic spring 304 is arranged between the telescopic column 3 and the telescopic groove 302, a connecting through hole 303 is opened in the screw sleeve 206, and the telescopic column 3 is connected to the splint 4 through the connecting through hole 303.

[0051] When the screw sleeve 206 performs linear motion on the screw rod 205 , since the telescopic column 3 is connected to the clamping plate 4 through the connecting through hole 303 of the screw sleeve 206 , the movement of the screw sleeve 206 will drive the clamping plate 4 to move synchronously.

[0052] During this process, the telescopic column 3 slides in the telescopic groove 302 of the screw rod 205, and the telescopic spring 304 is compressed or stretched.

[0053] For example, when the clamping plate 4 is disturbed by external force, or when the device is irregular in shape causing uneven force on different parts, the telescopic column 3 will produce relative displacement in the telescopic groove 302, and the telescopic spring 304 buffers this displacement by its own elasticity.

[0054] During the equipment detection process, if vibration or slight displacement of the equipment occurs, the telescopic spring 304 can generate a reverse force in real time to compensate for the displacement change caused by external force, push the telescopic column 3 back to the initial position or adjust to a new equilibrium position, so that the clamp 4 can continue to stably clamp the electrical automation equipment.

[0055] Furthermore, due to the adaptability between the telescopic column 3 and the telescopic slot 302 , the distance change between the clamping plate 4 and the screw rod 205 under different motion states can be adapted to ensure smooth operation of the entire device.

[0056] The combination of the telescopic spring 304 and the telescopic column 3 provides a buffering function for the clamping plate 4, thereby preventing the clamping plate 4, the screw rod 205 and the connecting parts from being damaged due to sudden impact force or rigid collision.

[0057] Especially in dynamic operations such as rapid clamping and flipping of equipment, the buffering effect can significantly extend the service life of various components of the device and reduce maintenance costs.

[0058] For electrical automation equipment of different shapes and sizes, the degree of contact and the reaction force between the equipment and the clamping plate 4 are different.

[0059] The telescopic spring 304 can adapt to this difference and dynamically adjust the clamping force of the clamping plate 4 to ensure that the device is firmly clamped and does not become loose locally due to irregular shapes, thereby maintaining good testing conditions.

[0060] During the long-term operation of the detection device, slight displacement deviations are likely to occur between the components due to factors such as mechanical vibration, thermal expansion and contraction.

[0061] The telescopic column 3 and the telescopic spring 304 can effectively offset such deviations, so as to maintain a stable connection between the clamping plate 4 and the screw rod 205, thereby ensuring the stability of the entire detection device and making the detection results more accurate and reliable.

[0062] When the driving component drives the splint 4 to perform complex movements such as flipping and translation, the flexible sliding of the telescopic column 3 in the telescopic groove 302, combined with the elastic force assistance of the telescopic spring 304, can ensure smooth transition of movement, avoid problems such as jamming and difficulty that affect the smoothness of movement, and improve the overall operating efficiency of the detection device.

[0063] Furthermore, a turning groove 301 is provided on the outer side of the screw sleeve 206 . The turning groove 301 is connected to the limiting groove 207 . The turning groove 301 is spirally arranged, and there is an angle of 180° between the cutting end and the sliding end of the turning groove 301 .

[0064] The motor 202 drives the screw rod 205 to rotate, and the screw sleeve 206 can only make axial linear motion along the screw rod 205 due to the cooperation between the outer limiting groove 207 and the limiting protrusion 204 on the limiting plate 203.

[0065] During this process, the telescopic column 3 connected to the screw sleeve 206 through the connecting through hole 303 drives the clamping plate 4 and the electrical automation equipment clamped therein to move smoothly, which may be to approach the detection camera or perform other position adjustments before detection.

[0066] When the screw sleeve 206 moves to a specific position, the limiting protrusion 204 continues to move along the limiting groove 207 and enters into the flip groove 301 connected to the limiting groove 207 .

[0067] Since the flip groove 301 is spirally arranged and there is an angle of 180° between its cutting end and sliding end, as the screw 205 continues to rotate, the screw sleeve 206 cannot continue to maintain simple linear motion, but will rotate around the axis of the screw 205 under the guidance of the spiral structure.

[0068] The rotation of the screw sleeve 206 is transmitted to the telescopic column 3 through the connecting through hole 303, thereby driving the clamping plate 4 to rotate synchronously, and finally realizing the electrical automation equipment clamped by the clamping plate 4 to flip 180 degrees.

[0069] In this way, the bottom surface of the equipment, which was originally located at the bottom and difficult to be observed by the inspection camera, can be completely exposed to the field of view of the inspection camera, making it convenient for comprehensive inspection.

[0070] By cleverly arranging the flip groove 301, the device can automatically flip 180 degrees, so that the detection camera can view the bottom surface of the device without omission.

[0071] This greatly enhances the comprehensiveness of the inspection, avoids missing possible appearance defects, loose parts or assembly abnormalities on the bottom of the equipment, and improves the inspection quality.

[0072] The entire flipping process is triggered by the motor 202 driving the screw 205 to rotate, and there is no need for manual flipping of the device.

[0073] Compared with manual operation, automated flipping is more precise and efficient. It not only saves labor costs, but also reduces the risk of secondary damage to equipment caused by uneven force and inaccurate angles of manual flipping, thereby ensuring the stability of the inspection process.

[0074] The flipping function is realized by utilizing the flipping groove 301 opened on the screw sleeve 206 without adding a large and complex flipping mechanism, which makes the structure of the entire detection device more compact and integrates more functions in a limited space, which is conducive to the miniaturized design of the device and facilitates flexible installation and use in different venues.

[0075] Due to the spiral shape of the flip groove 301 and the precise 180° angle design, the flip angle of the equipment is precisely controllable, ensuring that the bottom surface can be accurately aligned with the inspection camera every time it flips, which helps to standardize subsequent inspection work such as image analysis and defect judgment, and improves the reliability of the inspection results.

[0076] Furthermore, there are four limiting protrusions 204, four limiting grooves 207, and four turning grooves 301, which are spaced apart in a circular array with the axis of the screw rod 205 as the center.

[0077] When the motor 202 drives the screw rod 205 to rotate, the four limiting protrusions 204 distributed in a circular array cooperate with the corresponding limiting grooves 207 respectively, so that the four screw sleeves 206 can synchronously perform axial linear motion along the screw rod 205.

[0078] During the linear motion stage, since each screw sleeve 206 is connected to the corresponding telescopic column 3 and the clamping plate 4 through the connecting through hole 303, the multiple clamping plates 4 will work together to steadily apply a uniform clamping force to the electrical automation equipment, ensuring the stability of the equipment during movement and avoiding tilting and shaking due to uneven force.

[0079] When the device needs to be turned over, the limiting protrusions 204 on each screw sleeve 206 will enter the corresponding turning groove 301 in sequence.

[0080] Since the turning groove 301 is spirally arranged and the angle between the cutting end and the sliding end is 180°, as the screw rod 205 continues to rotate, each screw sleeve 206 will rotate around the axis of the screw rod 205, driving the telescopic column 3 and the clamping plate 4 connected thereto to turn over.

[0081] The structures of the four circular arrays operate simultaneously, exerting force from multiple angles, so that the device clamped by the clamp 4 can complete a 180° flip in a stable and balanced manner.

[0082] This method of synchronously flipping multiple structures is like applying force evenly from all sides of the device. Compared with flipping a single structure, it greatly reduces the probability of twisting and deflection of the device due to uneven local force during the flipping process.

[0083] The plurality of limiting protrusions 204, limiting grooves 207 and flipping grooves 301 are distributed in a circular array, ensuring that when the device is moved and flipped, the clamping plate 4 applies forces from multiple directions, so that the device is stably supported in all directions.

[0084] Whether it is large-scale heavy electrical equipment or special equipment with complex structure and uneven center of gravity, it can maintain a stable posture during the detection process, effectively improve the detection accuracy and reduce the detection error caused by shaking.

[0085] Furthermore, a rubber pad 402 is provided on the inner side of the movable sheet 401 .

[0086] When the clamping plate 4 clamps the electrical automation device, the movable piece 401 will adjust its position adaptively according to the shape of the device under the pressure of the device shell.

[0087] At this time, the rubber pad 402 inside the movable sheet 401 is in direct contact with the surface of the device.

[0088] The rubber pad 402 is soft and has a certain elasticity. It can deform according to the slight undulations and irregular shapes of the device housing at the moment of contact, fill in possible tiny gaps, and thus increase the contact area with the device surface.

[0089] During the entire testing process, the rubber pad 402 tightly "grasps" the device housing by virtue of its own friction characteristics, and assists the movable sheet 401 to maintain a stable clamping state.

[0090] Electrical automation equipment often has a precise structure and a smooth shell, and rigid contact can easily cause scratches and wear.

[0091] The presence of rubber pad 402 is like putting a layer of "soft armor" on the device, isolating the rigid collision between the movable piece 401 and the device casing, effectively avoiding damage to vulnerable parts such as the device's paint surface, display screen, and fine interfaces during the clamping process, and reducing the risk of equipment loss.

[0092] When the rubber pad 402 contacts the device housing, it will be deformed moderately, and this deformation will generate greater friction between the rubber pad 402 and the device.

[0093] Compared with the case without rubber pads, the increase in friction can significantly enhance the clamping force of the movable sheet 401 on the device. Even if the device is disturbed by external forces such as slight vibration and shaking, it can be firmly fixed in the detection position to ensure detection accuracy.

[0094] The shapes of the shells of different electrical automation equipment vary greatly, and some have irregular structures such as protrusions and grooves.

[0095] The soft rubber pad 402 can conform to these irregular surfaces and fit tightly, ensuring that it can still provide a stable and uniform clamping effect for the device under complex shapes, further expanding the adaptability of the detection device to different devices.

[0096] During the operation of the detection device, mechanical transmission, equipment flipping and other actions may generate vibration and noise. The rubber pad 402 can absorb part of the vibration energy and buffer the vibration impact caused by clamping. Furthermore, a limit ring 305 is provided at the other end of the telescopic column 3 , and the limit ring 305 is adapted to the telescopic slot 302 and can only slide in the telescopic slot 302 along the inner wall thereof.

[0097] During the operation of the entire detection device, when the motor 202 drives the screw 205 to rotate and the screw sleeve 206 moves axially or rotates around the screw 205, the telescopic column 3 connected to the screw sleeve 206 through the connecting through hole 303 will move synchronously therewith.

[0098] Since the limiting ring 305 arranged at the other end of the telescopic column 3 is located in the telescopic slot 302 of the screw rod 205 and the limiting ring 305 is adapted to the telescopic slot 302 , when the telescopic column 3 generates telescopic displacement under the action of the telescopic spring 304 , the limiting ring 305 will slide along the inner wall of the telescopic slot 302 .

[0099] On the one hand, this sliding fit limits the range of the telescopic column 3 from leaving the telescopic slot 302. On the other hand, it provides precise guidance for the movement trajectory of the telescopic column 3, so that it can only move along the predetermined axial path of the telescopic slot 302, avoiding abnormal situations such as deviation, shaking, collision, and jamming with the screw 205 due to external interference.

[0100] The limiting ring 305 acts as a mechanical limiting device to firmly limit the telescopic column 3 in the telescopic slot 302 .

[0101] In an environment where the detection device is frequently operated and vibrates for a long time, even if it encounters a sudden large impact force or abnormal spring elastic force, the telescopic column 3 will not fall out of the telescopic slot 302, thereby ensuring the integrity of the entire transmission and connection structure, avoiding device failure caused by component detachment, and reducing maintenance frequency and cost.

[0102] The telescopic groove 302 is a limiting ring 305 , that is, a unique “track” is set for the movement of the telescopic column 3 .

[0103] This ensures that the telescopic column 3 strictly follows a predetermined route each time it moves and retracts, thereby making the movement of the splint 4 connected thereto more precise and standardized.

[0104] Precise motion control is critical for electrical automation equipment testing. It can ensure that the equipment reaches the testing position accurately and that the angle is correct during operations such as flipping, thereby improving testing accuracy.

[0105] With the close cooperation between the limiting ring 305 and the telescopic slot 302 , unnecessary shaking and swinging of the telescopic column 3 are reduced, thereby improving the mechanical stability of the entire device.

[0106] The stable mechanical structure can provide continuous and stable output when dealing with complex and changeable detection tasks, avoiding errors in the detection results due to accumulation of tiny jitters or displacement deviations, and ensuring the reliability of the detection results.

[0107] The limiting ring 305 avoids improper friction and collision between the telescopic column 3 and the internal structure of the screw rod 205, thereby reducing the wear rate of the components.

[0108] During long-term and repeated testing operations, each component can maintain a good working condition, which prolongs the service life of key components such as the telescopic column 3 and the screw 205, and improves the durability of the testing device as a whole.
