Description

Technical Field

[0001] This invention relates to the field of power supply testing technology, and more specifically to a distributed power supply access unit testing station. Background Technology

[0002] As a core supporting equipment of the distributed power grid-connected system, the distributed power access unit undertakes key functions such as power metering, grid-connected protection, data acquisition and transmission, islanding detection and linkage control between the distributed power source and the distribution network. In order to ensure the grid-connected performance of the distributed power access unit, multi-dimensional performance testing needs to be carried out before commissioning. This includes testing the accuracy of electrical parameter acquisition such as voltage, current, frequency and power, as well as testing the data upload and command reception capabilities of its communication interface and the reliability of electrical connections of each interface. This ensures that all performance parameters meet the national standards and industry technical requirements for distributed power grid connection. Generally, most testing operations are carried out in a mode of manual operation combined with semi-automated testing equipment. During the testing process, manual operation is required to complete a series of operations such as loading, positioning, plugging in the testing interface, unloading and transferring the unit after testing. Firstly, testing is currently conducted manually in conjunction with semi-automated equipment, which incurs relatively high labor costs. Furthermore, manual operation is prone to issues such as positioning errors and inaccurate connections, affecting testing accuracy and efficiency, making it unsuitable for the large-scale, streamlined production testing needs of distributed power access units. Additionally, contact and friction with the equipment during manual operation can generate static electricity, which may interfere with test data, further impacting the stability and accuracy of the testing process. Therefore, we propose a distributed power access unit testing platform. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a distributed power access unit testing station, which effectively solves the problems of high labor costs, significant impact on testing accuracy and efficiency due to manual operation, and the potential for electrostatic interference from manual contact and friction, making it difficult to adapt to the testing needs of large-scale production lines.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a distributed power access unit testing station, including a main unit, a testing station body, and a conveying mechanism disposed on the testing station body, comprising, The detection unit includes a positioning mechanism disposed on the detection platform body for positioning and fixing the distributed power access unit, and a detection mechanism disposed on the detection platform body, which is used to perform detection when the distributed power access unit is positioned. The transfer unit includes a lifting mechanism mounted on the testing platform body for lifting the distributed power access unit, a guiding mechanism mounted on the testing platform body for guiding and limiting the movement trajectory of the positioning mechanism, and a driving mechanism mounted on the testing platform body. The driving mechanism is used to cooperate with the guiding mechanism to transfer the distributed power access unit that has completed testing.

[0005] Furthermore, the lifting mechanism includes a U-shaped baffle disposed at one end of the conveying mechanism for receiving the distributed power access unit to be tested, and the bottom of the U-shaped baffle is fixedly connected to the inner wall of the testing platform body.

[0006] Furthermore, a support plate for lifting the distributed power access unit to be tested is provided below the U-shaped baffle. An electric cylinder is provided at the bottom of the support plate. The fixed end of the electric cylinder is fixedly connected to the inner wall of the test platform body, and the output end of the electric cylinder is fixedly connected to the bottom of the support plate.

[0007] Furthermore, the guiding mechanism includes an L-direction guide plate fixedly connected to the top of the detection platform body, an oblique guide plate slidably connected to the inner wall of the L-direction guide plate, and a fixed shaft for connecting to the positioning mechanism slidably connected to the inner walls of the L-direction guide plate and the oblique guide plate.

[0008] Furthermore, the driving mechanism includes a motor fixedly connected to the inner wall of the detection platform body, a crank fixedly connected to the motor via an output shaft, a connecting rod two rotatably connected to the end of the crank away from the motor, and a connecting rod two rotatably connected to the side of the inclined guide plate away from the L-direction guide plate at the end away from the crank.

[0009] Furthermore, the positioning mechanism includes a fixed frame fixedly connected to one end of a fixed shaft, and an electric cylinder fixedly connected to the top of the fixed frame.

[0010] Furthermore, a fixed block is fixedly connected to the output end of the electric cylinder, and multiple sets of connecting rods are rotatably connected to the surface of the fixed block. Each set of connecting rods is rotatably connected to a slider at the end away from the fixed block, and a guide rail is slidably connected to the surface of the slider. The bottom of the guide rail is fixedly connected to the inner wall of the fixed frame.

[0011] Furthermore, each of the multiple sets of sliders has a flexible clamping plate fixedly connected to its bottom for clamping and fixing the distributed power access unit, and the multiple sets of flexible clamping plates are arranged in a circumferential distribution.

[0012] Furthermore, the testing mechanism includes an electric cylinder two fixedly connected to the inner wall of the testing platform body, a slider two fixedly connected to the output end of the electric cylinder two, a guide rail two slidably connected to the surface of the slider two, and the bottom of the guide rail two fixedly connected to the inner wall of the testing platform body.

[0013] Furthermore, a sleeve is fixedly connected to the bottom of the second slider, and a detection plug for plugging into the interface of the distributed power access unit is fixedly connected to the inner wall of the sleeve. The output end of the detection plug is connected to an external detection device through a flexible wire.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to embodiments.

[0020] like Figures 1 to 9As shown, a distributed power access unit testing platform includes a main unit 100, including a testing platform body 101 and a conveying mechanism 102 disposed on the testing platform body 101. The platform includes a testing unit 200, comprising a positioning mechanism 201 disposed on the testing platform body 101 for positioning and fixing the distributed power access unit, and a testing mechanism 202 disposed on the testing platform body 101. The testing mechanism 202 is used for testing when the distributed power access unit is positioned. A transfer unit 300 includes a lifting mechanism 3 disposed on the testing platform body 101 for lifting the distributed power access unit. 01. A guide mechanism 302, installed on the testing platform body 101, is used to guide and limit the movement trajectory of the positioning mechanism 201. A drive mechanism 303, installed on the testing platform body 101, is used to cooperate with the guide mechanism 302 to transfer the distributed power access unit that has completed testing. The main unit 100 includes the testing platform body 101 and the conveying mechanism 102. The conveying mechanism 102 consists of two independent conveyor belts. Conveyor belt one is used to convey the distributed power access unit to be tested to the lifting mechanism 301 of the transfer unit 300. Conveyor belt two is used to transfer the distributed power access unit that has completed testing. Specifically, refer to Figure 2 and Figure 7 The lifting mechanism 301 includes a U-shaped baffle 3013 disposed at one end of the conveying mechanism 102 for receiving the distributed power supply access unit to be tested. The bottom of the U-shaped baffle 3013 is fixedly connected to the inner wall of the testing platform body 101. Below the U-shaped baffle 3013, a lifting plate 3012 is disposed for lifting the distributed power supply access unit to be tested. An electric cylinder 3011 is disposed at the bottom of the lifting plate 3012. The fixed end of the electric cylinder 3011 is fixedly connected to the inner wall of the testing platform body 101, and the output end of the electric cylinder 3011 is fixedly connected to the lifting plate 3012. 12 Bottom; The lifting mechanism 301 is the core component for loading and lifting the access unit to be tested. The U-shaped baffle 3013 is fixedly connected to the inner wall of the testing table body 101 and is correspondingly set at the output end of the conveyor belt of the conveying mechanism 102. It is used to receive the distributed power access unit to be tested conveyed from the first conveyor belt. The slot of the U-shaped baffle 3013 matches the output end of the first conveyor belt to ensure that the access unit to be tested can be directly moved into the U-shaped baffle 3013 and completely separated from the first conveyor belt, so as to avoid static electricity caused by the relative friction between the continuous movement of the conveyor belt and the unit. It should be noted that a lifting plate 3012 is installed below the U-shaped baffle 3013. The bottom of the lifting plate 3012 is fixedly connected to the output end of the electric cylinder 3011. The fixed end of the electric cylinder 3011 is fixed to the inner wall of the detection table body 101. The electric cylinder 3011 provides power for the lifting of the lifting plate 3012. A photoelectric sensor is installed next to the U-shaped baffle 3013. When the photoelectric sensor detects that the distributed power supply access unit to be tested has completely detached from the conveyor belt and entered the U-shaped baffle 3013, the electric cylinder 3012 will lift the load. When cylinder 3011 starts, its output end extends upward, driving the lifting plate 3012 to move upward, lifting the unit to be tested in the U-shaped baffle 3013 to the clamping position of the positioning mechanism 201, completing the loading and lifting action. After the positioning mechanism 201 clamps and fixes the unit, the output end of electric cylinder 3011 retracts downward, driving the lifting plate 3012 to descend and reset, facilitating the entry of the next set of units to be tested into the U-shaped baffle 3013, and lifting the next set of units to be tested. Specifically, refer to Figure 2 , Figure 8 and Figure 9 The guiding mechanism 302 includes an L-direction guide plate 3021 fixedly connected to the top of the detection table body 101, an inclined guide plate 3022 slidably connected to the inner wall of the L-direction guide plate 3021, and a fixed shaft 3023 for connecting to the positioning mechanism 201 slidably connected to the inner walls of the L-direction guide plate 3021 and the inclined guide plate 3022. The driving mechanism 303 includes a motor 3031 fixedly connected to the inner wall of the detection table body 101, a crank 3032 fixedly connected to the motor 3031 via an output shaft, a connecting rod 3033 rotatably connected to the end of the crank 3032 away from the motor 3031, and a connecting rod 3033 rotatably connected to the side of the inclined guide plate 3022 away from the L-direction guide plate 3021 at the end away from the crank 3032. The guiding mechanism 302 and the driving mechanism 303 are connected to the L-direction guide plate 3021. Mechanism 303 works in conjunction with positioning mechanism 201 to provide trajectory guidance and power for the movement of the unit after the test is completed. The L-direction guide plate 3021 of the guiding mechanism 302 is fixedly connected to the top of the test table body 101. The inner wall of the L-direction guide plate 3021 is slidably connected to the inclined guide plate 3022. The surface of the L-direction guide plate 3021 is provided with an L-shaped guide groove, while the surface of the inclined guide plate 3022 is provided with an inclined guide groove. At the same time, the common inner wall of the L-direction guide plate 3021 and the inclined guide plate 3022 is slidably connected to the fixed shaft 3023. One end of the fixed shaft 3023 is connected to the positioning mechanism 201 and can slide along the guide trajectory of the L-direction guide plate 3021 and the inclined guide plate 3022, thereby driving the positioning mechanism 201 to move synchronously. It should be noted that the motor 3031 of the drive mechanism 303 is fixedly connected to the inner wall of the detection table body 101, providing power for the entire transfer action. The output shaft of the motor 3031 is fixedly connected to the crank 3032. The end of the crank 3032 away from the motor 3031 is rotatably connected to the second connecting rod 3033. The end of the second connecting rod 3033 away from the crank 3032 is rotatably connected to the side of the inclined guide plate 3022 away from the L-direction guide plate 3021. When the motor 3031 starts, the output shaft drives the crank 3032 to rotate in a circle. The crank 3032 converts the circular motion into the linear sliding of the inclined guide plate 3022 through the second connecting rod 3033. While the inclined guide plate 3022 slides along the inner wall of the L-direction guide plate 3021, it drives the fixed shaft 3023 to slide along the guide groove of the L-direction guide plate 3021 and the inclined guide plate 3022, ultimately realizing the precise movement of the positioning mechanism 201. Specifically, refer to Figures 2 to 4 The positioning mechanism 201 includes a fixed frame 2011 fixedly connected to one end of a fixed shaft 3023. An electric cylinder 2012 is fixedly connected to the top of the fixed frame 2011. A fixed block 2016 is fixedly connected to the output end of the electric cylinder 2012. Multiple sets of connecting rods 2013 are rotatably connected to the surface of the fixed block 2016. Slider 2014s are rotatably connected to the ends of the multiple sets of connecting rods 2013 away from the fixed block 2016. Guide rails 2015 are slidably connected to the surfaces of the multiple sets of sliders 2014. The bottom of the guide rails 2015 is fixedly connected to the inner wall of the fixed frame 2011. Flexible clamping plates 2017 for clamping and fixing the distributed power access unit are fixedly connected to the bottom of each set of sliders 2014. The flexible clamping plates 2017 are arranged circumferentially. The fixed frame 2011 is fixedly connected to one end of the fixed shaft 3023 of the guide mechanism 302. The device can move synchronously with the sliding of the fixed shaft 3023. The top of the fixed frame 2011 is fixedly connected to the electric cylinder 2012. The output end of the electric cylinder 2012 is fixedly connected to the fixed block 2016 to provide power for the clamping action. Multiple sets of connecting rods 2013 are rotatably connected to the surface of the fixed block 2016. The end of each connecting rod 2013 away from the fixed block 2016 is rotatably connected to the slider 2014. Multiple sets of sliders 2014 are slidably connected to the surface of the guide rail 2015. The guide rail 2015 is fixedly connected to the inner wall of the fixed frame 2011 to provide trajectory guidance for the sliding of the sliders 2014. The bottom of multiple sets of sliders 2014 is fixedly connected to the flexible clamping plate 2017. The multiple sets of flexible clamping plates 2017 are circumferentially distributed to adapt to the shape structure of the distributed power access unit and realize circumferential clamping and positioning of the unit. It should be noted that after the lifting mechanism 301 lifts the access unit to be tested to the clamping station, the electric cylinder 2012 is started, driving the fixed block 2016 to move upward. The fixed block 2016 pulls multiple sliders 2014 along the guide rail 2015 synchronously towards the center through multiple sets of connecting rods 2013, thereby driving multiple sets of flexible clamping plates 2017 to move closer to the center, realizing precise clamping and fixed positioning of the distributed power access unit. One side of the flexible clamping plate 2017 is made of anti-static flexible material, which not only avoids damage to the unit shell during clamping, but also prevents the generation of static electricity. After the test is completed, the access unit is transferred to the second conveyor belt, and the electric cylinder 2012 is started again, driving the fixed block 2016 to move downward. Through the connecting rod 2013, the slider 2014 is pushed to slide outward along the guide rail 2015. The flexible clamping plates 2017 open outward at the same time, releasing the clamping of the unit, and the second conveyor belt continues to transport it to the next station. Specifically, refer to Figure 2 , Figure 5 and Figure 6 The testing mechanism 202 includes an electric cylinder 2021 fixedly connected to the inner wall of the testing platform body 101. A slider 2023 is fixedly connected to the output end of the electric cylinder 2021. A guide rail 2022 is slidably connected to the surface of the slider 2023. The bottom of the guide rail 2022 is fixedly connected to the inner wall of the testing platform body 101. A retaining sleeve 2024 is fixedly connected to the bottom of the slider 2023. A testing plug 2025 for insertion into the interface of a distributed power supply access unit is fixedly connected to the inner wall of the retaining sleeve 2024. The output end of the testing plug 2025 is connected to external testing equipment via a flexible wire 2026. The electric cylinder 2021 is fixedly connected to the inner wall of the testing platform body 101 for testing... The insertion of the test plug 2025 provides power. The output end of the electric cylinder 2021 is fixedly connected to the slider 2023. The slider 2023 is slidably connected to the surface of the guide rail 2022. The guide rail 2022 is fixedly connected to the inner wall of the test platform body 101, providing trajectory guidance for the sliding of the slider 2023. The bottom of the slider 2023 is fixedly connected to the sleeve 2024. The inner wall of the sleeve 2024 is fixedly connected to the test plug 2025. The output end of the test plug 2025 is connected to the external test equipment through the flexible wire 2026. The position of the test plug 2025 is precisely matched with the interface position of the distributed power access unit after being clamped and fixed by the positioning mechanism 201. It should be noted that when the positioning mechanism 201 completes the clamping and positioning of the unit, and the lifting plate 3012 of the lifting mechanism 301 descends and resets, the electric cylinder 2021 starts synchronously, and the output end extends to drive the slider 2023 to slide along the guide rail 2022 towards the unit, thereby driving the test plug 2025 to be accurately inserted into the interface of the distributed power access unit. The external testing equipment is connected to the test plug 2025 through the flexible wire 2026 and begins to perform various performance tests on the unit. After the test is completed, the output end of the electric cylinder 2021 retracts, driving the slider 2023 to slide in the opposite direction along the guide rail 2022, and the test plug 2025 is pulled out from the unit interface, completing the testing action.

[0021] The working principle of this invention: After the equipment is started, the entire testing platform enters the initialization state. The two independent conveyor belts of the conveying mechanism 102 start and maintain a uniform speed. The electric cylinder 3011 of the lifting mechanism 301 is in the retracted reset state. The lifting plate 3012 is attached to the inner wall of the testing platform body 101, forming a waiting station with the U-shaped baffle 3013. The electric cylinder 2012 of the positioning mechanism 201 is in the retracted state. Multiple sets of flexible clamps 2017 are in the open state, preparing to clamp the unit to be tested. The electric cylinder 2021 of the testing mechanism 202 is in the retracted state. The testing plug 2025 is in the reset standby position, maintaining a safe distance from the testing station. At all distances, the motor 3031 of the drive mechanism 303 is in a stopped state, the inclined guide plate 3022 and the fixed shaft 3023 are in the initial guide position, the positioning mechanism 201 is facing the lifting position of the lifting mechanism 301, the external detection equipment completes the power-on self-test, and maintains circuit connection with the detection plug 2025 through the flexible wire 2026, and enters the detection state. The photoelectric sensor next to the U-shaped baffle 3013 completes the power-on calibration and is in the real-time detection state. All execution components and sensing components are interconnected with the PLC control system built into the bench, forming a closed-loop control link from sensing detection to signal transmission, then to command issuance, and finally mechanism action. The feeding conveyor belt of the conveying mechanism 102 uniformly transports the distributed power access unit to be tested to the U-shaped baffle 3013 of the lifting mechanism 301. The slot of the U-shaped baffle 3013 is precisely matched with the output end of the feeding conveyor belt. The access unit to be tested can slide directly into the U-shaped baffle 3013 and gradually detach from the feeding conveyor belt. During this process, the photoelectric sensor adopts the through-beam sensing principle. The transmitting end continuously emits infrared light. When the unit to be detected is completely inserted into the U-shaped baffle 3013 and detached from the feeding conveyor belt, the unit body blocks the infrared light path of the photoelectric sensor. The receiving end has no signal feedback. The sensor immediately transmits the material to be detected electrical signal to the PLC control system, so that the unit to be detected is completely detached from the moving conveyor belt, avoiding static electricity generated by relative friction between the unit and the conveyor belt, and reducing the interference of static electricity on subsequent detection. After receiving the position signal from the photoelectric sensor, the PLC control system immediately sends an action command to the lifting mechanism 301. Upon receiving the command, the electric cylinder 3011 starts and extends its output end, driving the bottom-fixed lifting plate 3012 to move upward at a constant speed in the vertical direction. The lifting plate 3012 lifts the unit to be tested from below the U-shaped baffle 3013 and transports it upward to the clamping position of the positioning mechanism 201. After receiving the stroke limit signal, the electric cylinder 3011 stops its action. After the access unit to be tested is lifted to the clamping station, the PLC control system sends a clamping and positioning command to the positioning mechanism 201. The electric cylinder 2012 is started, which drives the fixed block 2016 at its bottom to move upward synchronously. When the fixed block 2016 moves upward, the multiple sets of connecting rods 2013 rotatably connected to its surface pull the slider 2014 rotatably connected to its bottom. The slider 2014 slides synchronously towards the center position along the guide rail 2015 on the inner wall of the fixed frame 2011. While the slider 2014 slides, it drives the flexible clamping plate 2017 at its bottom to move towards the center synchronously. Since the multiple sets of flexible clamping plates 2017 are circumferentially distributed, the distributed power access unit can be flexibly clamped from multiple directions until the clamping plate is tightly attached to the unit shell, thus completing the precise positioning and firm fixation of the unit. During this process, the flexible clamp 2017 uses an anti-static flexible material, which avoids damage to the unit shell by hard clamping and prevents static electricity from being generated due to contact friction during clamping. The extension stroke of the electric cylinder 2012 is precisely controlled by the PLC to ensure that the clamping force is moderate, which can prevent the unit from shifting during the testing process and will not cause deformation of the unit shell or damage to internal components due to excessive clamping. After positioning is completed, the electric cylinder 3011 receives the reset command from the PLC, retracts the output end to drive the lifting plate 3012 to descend to the initial position, prepares for the loading of the next set of connected units to be tested, and at the same time reserves sufficient working space for the insertion action of the testing mechanism 202. After the positioning mechanism 201 completes the clamping and positioning of the unit and the lifting plate 3012 is reset, the PLC control system sends a detection and insertion command to the detection mechanism 202. The electric cylinder 2021 starts and drives the slider 2023 fixed at its top to slide at a constant speed along the guide rail 2022 on the inner wall of the detection table body 101 towards the distributed power access unit that has been positioned. While the slider 2023 slides, it drives the detection plug 2025 fixed at its bottom by the sleeve 2024 to move synchronously. With the positioning mechanism 201, the position of the detection plug 2025 can be accurately matched with the position of the wiring interface of the unit. Finally, the detection plug 2025 can be smoothly and accurately inserted into the corresponding interface of the distributed power access unit to complete the physical connection of the detection circuit. After the test plug 2025 is inserted into the unit interface, it forms a complete test circuit with the external test equipment through the flexible wire 2026 connected to its output end. The flexible wire 2026 has the characteristics of being resistant to bending and having stable conductivity. It can adapt to the movement of the test plug 2025 and at the same time ensure the stability of the test signal transmission. After the external test equipment establishes an electrical connection and signal interaction with the unit to be tested through the test plug 2025, it automatically carries out the test according to the preset test program. After receiving the detection completion signal from the external detection equipment, the PLC control system immediately sends a reset command to the detection mechanism 202. The electric cylinder 2021 starts and retracts its output end, driving the slider 2023 to slide in the opposite direction along the guide rail 2022. The detection plug 2025 is smoothly pulled out from the interface of the distributed power supply access unit and returns to the initial standby position, completing the action reset of the detection process. After the detection plug 2025 is reset, the PLC control system sends a transfer command to the drive mechanism 303. The motor 3031 starts and drives the crank 3032, whose output shaft is fixed, to rotate in a circle. The crank 3032, through the connecting rod 3033 rotatably connected to its end, converts the circular motion into linear sliding of the inclined guide plate 3022, causing the inclined guide plate 3022 to slide in a direction along the inner wall of the L-direction guide plate 3021. Since the fixed shaft 3023 is simultaneously slidably connected to the guide grooves of both the L-direction guide plate 3021 and the inclined guide plate 3022, and the fixed shaft 3023 is fixed to the positioning mechanism 201... When the frame 2011 is fixedly connected and the inclined guide plate 3022 slides, it will drive the fixed shaft 3023 to move linearly along the L-shaped guide trajectory of the L-direction guide plate 3021, and move to the top of the second conveyor belt. Then, as the inclined guide plate 3022 is continuously pulled by the second connecting rod 3033, the fixed shaft 3023 can descend along the inclined guide plate 3022 and the L-direction guide plate 3021, driving the positioning mechanism 201 and the clamping detection completion unit to move synchronously until the positioning mechanism 201 moves precisely to the top of the unloading conveyor belt of the conveying mechanism 102, maintaining a small distance from the second conveyor belt, and completing the transfer guidance. After the positioning mechanism 201 moves above the unloading conveyor belt, the PLC control system sends a release command to the positioning mechanism 201. The electric cylinder 2012 starts, driving the fixed block 2016 to move downward. Through the connecting rod 2013, it pushes multiple sets of sliders 2014 to slide outward along the guide rail 2015. The flexible clamp 2017 opens simultaneously, releasing the clamp on the inspection completed unit. The unit falls onto the unloading conveyor belt under the action of gravity and is transferred by the unloading conveyor belt to the subsequent sorting, packaging and other stations to complete the unloading operation of a single inspection. After the material is unloaded, the PLC control system sends a reset command to the drive mechanism 303. The motor 3031 rotates in the reverse direction, and through the transmission of the crank 3032 and connecting rod 3033, it drives the inclined guide plate 3022 and the fixed shaft 3023 to move in the reverse direction along the guide trajectory. The positioning mechanism 201 returns to its initial clamping position, preparing for the positioning of the next set of units to be tested. The above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
