Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a quality inspection robot for power distribution cabinet factory testing. Background Technology

[0002] Defect inspection of the distribution cabinet surface is essential because the distribution cabinet must maintain its insulation effect during use. Therefore, anti-corrosion insulating paint is applied to the surface of the distribution cabinet during manufacturing. Before the distribution cabinet leaves the warehouse, a final inspection of its surface is required to ensure that there are no exposed metal parts.

[0003] Previously, electrical distribution cabinets were inspected manually by eye. However, with technological advancements, industrial cameras are increasingly being used to detect surface defects. Industrial camera inspection refers to the use of specific industrial camera systems in industrial production to inspect the surface of electrical distribution cabinets, identifying and recording potential defects such as scratches, dents, and cracks. This type of inspection typically involves machine vision technology and image processing algorithms. By analyzing images of the electrical distribution cabinet surface, automated defect detection and quality control can be achieved.

[0004] However, distribution cabinets have doors, and most existing visual inspection cameras cannot penetrate the doors to inspect the inside of the cabinet. Therefore, after inspecting the exterior of the distribution cabinet, it is still necessary to manually open the cabinet door and then inspect the inner walls of the door and the inside of the cabinet. This is time-consuming, labor-intensive, costly, and slow. Therefore, a quality inspection robot for the factory testing of distribution cabinets is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this utility model proposes a quality inspection robot for factory testing of power distribution cabinets.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The quality inspection robot for factory testing of power distribution cabinets according to this utility model includes a base, a robotic arm body, a power distribution cabinet body and a cabinet door. A testing chamber is fixedly installed on the outside of the base. The robotic arm body is fixedly installed inside the testing chamber, and a visual inspection camera is fixedly installed on the end face of the robotic arm body. A conveying device is fixedly installed on the top of the base. A limiting component is installed on the outside of the conveying device. The limiting component includes several limiting protrusions and two limiting rails. The limiting protrusions are fixedly installed at equal intervals on the conveyor belt of the conveying device. The two limiting rails are installed on both sides of the conveying device, and the distance between the two limiting rails is the same as the width of the power distribution cabinet body. The bottom end of one limiting rail is fixedly connected to the base, and the bottom end of the other limiting rail is slidably connected to the upper surface of the base. An electric push rod is fixedly connected to the side wall of the testing chamber, and the driving end of the electric push rod is fixedly connected to the side wall of the other limiting rail.

[0007] Preferably, the limiting rail includes a plate, and a plurality of equidistant omnidirectional balls are fixedly disposed on the side wall of the plate.

[0008] Preferably, the cabinet opening and the cabinet door of the power distribution cabinet are fitted with the limiting rails on the adjacent sides, the thickness of the cabinet door is less than the distance between the limiting rails and the limiting protrusions, and the limiting protrusions are located at the angle between the power distribution cabinet and the cabinet door.

[0009] Preferably, photoelectric sensors are fixedly installed on the upper surface of the base and the inner top wall of the detection chamber, and the photoelectric sensors are used to detect the conveying position of the power distribution cabinet.

[0010] Preferably, a rotating assembly is installed on the inner top wall of the testing chamber. The rotating assembly includes an electric slide table, which is fixedly installed on the inner top wall of the testing chamber.

[0013] Preferably, the card block is L-shaped, and a notch is provided at the center of the card block. The inside of the notch is rotatably connected to a side pressure member through a torsion spring shaft.

[0014] The advantages of this utility model are:

[0015] 1. This utility model places the power distribution cabinet between two limit bars.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-6As shown, the quality inspection robot for factory testing of the power distribution cabinet includes a base 1, a robotic arm body 2, a power distribution cabinet body 7, and a cabinet door 8. A testing chamber 3 is fixedly installed on the outside of the base 1. The robotic arm body 2 is fixedly installed inside the testing chamber 3, and a visual inspection camera 4 is fixedly installed on the end face of the robotic arm body 2. A conveying device 5 is fixedly installed on the top of the base 1. A limit component 6 is installed on the outside of the conveying device 5. The limit component 6 includes several limit protrusions 61 and two limit rails 62. The limit protrusions 61 are equidistantly fixed on the conveyor belt of the conveying device 5. The two limit rails 62 are installed on both sides of the conveying device 5, and the distance between the two limit rails 62 is the same as the width of the power distribution cabinet body 7. The bottom end of one limit rail 62 is fixedly connected to the base 1, and the bottom end of the other limit rail 62 is slidably connected to the upper surface of the base 1. An electric push rod 10 is fixedly connected to the side wall of the testing chamber 3. The driving end of the electric push rod 10 is fixedly connected to the side wall of the other limit rail 62. The cabinet opening and cabinet door of the power distribution cabinet body 7 are connected to the door opening and door door 8. Door 8 fits against the adjacent side limit bar 62. The thickness of cabinet door 8 is less than the distance between the limit bar 62 and the limit protrusion 61. The limit protrusion 61 is located at the angle between the power distribution cabinet body 7 and the cabinet door 8. The main body of the robotic arm 2 adopts a five-axis or six-axis robotic arm. According to the specific requirements of the appearance quality inspection of the power distribution cabinet, the operator writes the motion control program and detection algorithm of the main body of the robotic arm 2, thereby defining the motion path, detection point position, detection sequence and data processing method of the main body of the robotic arm 2, so that the main body of the robotic arm 2 can perform efficient and accurate inspection of the power distribution cabinet body 7 according to the predetermined process. The main body of the robotic arm 2 drives the vision inspection camera 4 to scan the internal components, front and top surfaces of the power distribution cabinet. The image processing algorithm is used to analyze the captured images to detect whether there are defects such as scratches, bumps, deformation, paint peeling, and rust on the surface of the power distribution cabinet. The algorithm can identify the edge, texture, color and other features in the image to determine whether there are abnormalities, and record the location, size and shape of the defects.

[0027] Specifically, the electric push rod 10 is controlled by a PLC controller. The extension and retraction of the electric push rod 10 causes the limit bar 62 to slide. The distance between the two limit bars 62 can be adjusted according to the size of the distribution cabinet 7, making it suitable for distribution cabinets of various sizes. The limit protrusion 61, in conjunction with the limit bar 62, limits the cabinet door 8, preventing excessive rotation during transport, improving stability, and maintaining the angle between the side wall of the distribution cabinet 7 and the cabinet door 8 at approximately 90°. The door is then transported by the conveying device 5. When the power distribution cabinet 7 is placed on the conveyor belt, the worker first rotates the cabinet door 8 90° to open it. Then, the power distribution cabinet 7 is placed between two limit bars 62. The limit bars 62 prevent the cabinet door 8 from closing accidentally during transportation, so that the power distribution cabinet 7 remains open when it is transported to the testing chamber 3. This allows the robotic arm body 2 to move the vision inspection camera 4 into the interior of the power distribution cabinet 7 for intelligent inspection. Moreover, the cabinet door 8 does not need to be opened manually during inspection, which can speed up the inspection efficiency.

[0028] The limiting rail 62 includes a plate 621, and a number of equidistant omnidirectional balls 622 are fixedly installed on the side wall of the plate 621.

[0029] Specifically, by using the universal ball 622 to stop the power distribution cabinet 7 and the cabinet door 8 for limiting, the friction of the power distribution cabinet 7 during transportation can be reduced, making the transportation of the power distribution cabinet 7 smoother.

[0030] A photoelectric sensor 11 is fixedly installed on the upper surface of the base 1 and the inner top wall of the detection chamber 3. The photoelectric sensor 11 is used to detect the conveying position of the power distribution cabinet 7.

[0031] Specifically, when the photoelectric sensor 11 passes through the power distribution cabinet 7, it sends a signal to the PLC controller to control the conveying device 5 to stop running, thereby achieving precise position control.

[0032] A rotating assembly 9 is installed on the inner top wall of the testing chamber 3. The rotating assembly 9 includes an electric slide table 91, which is fixedly installed on the inner top wall of the testing chamber 3. A servo motor 92 is fixedly connected to the slider of the electric slide table 91. A cylinder 93 is fixedly connected to the drive end of the servo motor 92. A clamp is installed on the drive end of the cylinder 93. The clamp includes a U-shaped bracket 94. The drive end of the cylinder 93 is fixedly connected to the bracket 94. An electric push rod 95 is fixedly connected to the top of the bracket 94. A pressure plate 96 is fixedly connected to the drive end of the electric push rod 95.

[0033] Specifically, after the front, top, and interior of the distribution cabinet 7 are inspected, the PLC controller controls the operation of the rotating component 9. The cylinder 93 extends, causing the clamp to descend, ensuring the inner top wall of the distribution cabinet 7 is level with the inner bottom wall of the support 94. The electric slide 91 moves the clamp towards the distribution cabinet 7, inserting the bottom of the clamp into the cabinet. Then, the electric push rod 95 lowers the pressure plate 96 to the top of the distribution cabinet 7, clamping the cabinet. The cylinder 93 retracts, causing the clamp and the distribution cabinet 7 to... The lifting mechanism allows the robotic arm 2 to move in conjunction with the vision inspection camera 4 to inspect the bottom surface of the power distribution cabinet 7. The servo motor 92 then rotates the power distribution cabinet 7, allowing its sides and rear to face the vision inspection camera 4 for inspection, thus achieving comprehensive inspection of the power distribution cabinet 7. Finally, after the servo motor 92 rotates 180 degrees, the cylinder 93 extends, causing the power distribution cabinet 7 to descend to its original position. Then, the electric push rod 95 retracts, and the electric slide 91 moves the clamp to separate it from the power distribution cabinet 7, allowing the inspected power distribution cabinet 7 to be transported away.

[0034] The side wall of the pressure plate 96 protrudes outward to form an extension layer 97, and a notch is provided at the center of the latch block 98. The inside of the notch is rotatably connected to the side pressure member 99 through a torsion spring shaft. The pressure plate 96 is located above the cabinet door 8.

[0035] Specifically, the pressure plate 96 applies lateral pressure to the inserted cabinet door 8 through the torsion spring shaft, causing the cabinet door 8 to abut against the lower side of the extension layer 97 at a 90° angle with the distribution cabinet body 7. The pressure plate 96 clamps the top of the distribution cabinet body 7 downwards, and the pressure plate 96 drives the extension layer 97 and the locking block 98 to descend. The locking block 98 descends to the top of the cabinet door 8, thereby limiting the cabinet door 8 and preventing the cabinet door 8 from shaking when the distribution cabinet body 7 rises and rotates, which would cause the cabinet door 8 to fail to accurately return to its original position when the distribution cabinet body 7 is placed laterally.

[0036] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Furthermore, based on the actual situation, a suitable PLC controller should be selected and electrically connected to the robotic arm body 2, vision inspection camera 4, electric push rod 10, electric push rod 2 95, cylinder 93, photoelectric sensor 11, servo motor 92, and conveying device 5 to meet control requirements. The specific connections and control sequence should refer to the working principle described below, where the electrical connections are completed according to the sequential working order of each electrical component. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of the electrical control.

[0037] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0038] Working principle: The power distribution cabinet 7 to be inspected is transported by the conveyor device 5. When the power distribution cabinet 7 is placed on the conveyor belt, the worker first rotates the cabinet door 8 90° to open it. Then the power distribution cabinet 7 is placed between two limit bars 62. The limit bars 62 can prevent the cabinet door 8 from closing accidentally during transportation, so that the power distribution cabinet 7 is kept open when it is transported to the inspection chamber 3. This makes it easy for the robotic arm body 2 to move the vision inspection camera 4 to the inside of the power distribution cabinet 7 and the front and top surfaces of the power distribution cabinet 7 to achieve intelligent inspection. Moreover, the cabinet door 8 does not need to be opened manually during inspection, which can speed up the inspection efficiency.

[0039] After the front, top, and interior of the power distribution cabinet 7 are inspected, the PLC controller controls the operation of the rotating component 9. The cylinder 93 extends, causing the clamp to descend, ensuring the inner top wall of the power distribution cabinet 7 is level with the inner bottom wall of the support 94. The electric slide 91 moves the clamp towards the power distribution cabinet 7, inserting the bottom of the clamp into the cabinet. Then, the electric push rod 95 lowers the pressure plate 96 to the top of the cabinet, clamping it. Finally, the cylinder 93 retracts, causing the clamp and cabinet 7 to rise, allowing the machine to... The robotic arm body 2 can drive the vision inspection camera 4 to move and inspect the bottom surface of the power distribution cabinet 7. The servo motor 92 drives the power distribution cabinet 7 to rotate 90° in one go, so that the sides and back of the power distribution cabinet 7 can face the vision inspection camera 4 for inspection, thereby realizing a full-face inspection of the power distribution cabinet 7. Finally, after the servo motor 92 rotates 180 degrees, the cylinder 93 extends and drives the power distribution cabinet 7 to descend to its original position. Then, the electric push rod 95 retracts and the electric slide 91 drives the fixture to move and separate from the power distribution cabinet 7, so that the power distribution cabinet 7 can be transported away after the inspection is completed.
