Description

Technical Field

[0001] This invention relates to the field of single-phase reactor manufacturing and processing technology, and in particular to a production line for automatic testing and assembly of single-phase reactor electrical performance products. Background Technology

[0002] As an important reactive power compensation and filtering device in power systems, the accuracy and stability of the electrical performance parameters (such as inductance, DC resistance, insulation resistance, and withstand voltage) of single-phase reactors directly affect the operational safety of the entire power system. Therefore, rigorous multi-stage electrical performance tests must be conducted before the finished reactors leave the factory.

[0003] Currently, the production and testing of single-phase reactors generally employs manual or semi-automated methods. Operators need to manually move the reactor under test to the testing station, connect the test cables, start the testing instruments, record the test data, and then determine whether the product is qualified based on the test results. This traditional operating mode has the following technical problems: First, the testing efficiency is low, making it difficult to meet the needs of large-scale production. Due to the large size and weight of reactor products, manual handling and wiring operations are time-consuming and labor-intensive. Furthermore, each product needs to undergo unloaded tests (such as withstand voltage, insulation resistance, DC resistance, inductance, etc.) and loaded tests (high current loading) sequentially. Multiple handling and wiring operations result in long testing cycles, limiting production capacity. Second, the labor intensity for operators is high, and there are safety hazards. During loaded tests, reactors need to withstand currents of hundreds or even thousands of amperes. Frequent manual insertion and removal of high-voltage, high-current test cables is not only cumbersome but also highly prone to electric shock accidents, posing a threat to the personal safety of operators.

[0004] In summary, the existing single-phase reactor electrical performance testing process suffers from low testing efficiency, high labor intensity for operators, and potential safety hazards. Summary of the Invention

[0005] This invention provides an automated assembly line for testing the electrical performance of single-phase reactors, which can solve the problems of low testing efficiency, high labor intensity for operators, and safety hazards in the existing single-phase reactor electrical performance testing process.

The line includes a clamping area, a waiting area, a testing area, an inspection area, an unloading area, a fixture plate, and a high-speed conveyor chain. The clamping area, waiting area, testing area, inspection area, and unloading area are sequentially arranged along the conveying direction of the high-speed conveyor chain, which is used for conveying the fixture plate. The clamping area is used to receive the fixture plate and clamp the single-phase reactor product onto the fixture plate according to a preset posture. The waiting area is used to receive and temporarily store fixture plates from the clamping area; The test area is used to receive the fixture plate from the waiting area and to perform electrical performance and functional tests on the single-phase reactor products on the fixture plate.

The waiting area is used to receive and temporarily store jig plates from the clamping area. Its core function is to buffer and coordinate the production cycle. The waiting area waits in real time for the response signal from the testing area. Only after confirming that the testing area station is zeroed and there is no material accumulation will the jig plate be released, ensuring that the testing area can receive the products to be tested in an orderly and efficient manner. The testing area, as the functional area of ​​this production line, is used to receive jig plates from the waiting area and perform comprehensive electrical performance functional tests on the single-phase reactor products on the jig plates to ensure that the product's electrical performance parameters meet the factory standards. The testing area includes a product posture adjustment device for precisely adjusting the posture of single-phase reactors on the fixture plate. The inspection area receives fixture plates from the testing area and performs visual inspections on the single-phase reactors, overcoming the limitations of electrical performance testing and achieving comprehensive product quality control. The off-line area, as the final station of the production line, receives fixture plates from the inspection area and removes the single-phase reactors from them. After off-line processing, the fixture plates are recycled and reused, reducing production costs.

[0008] This invention provides an automated assembly line for testing the electrical performance of single-phase reactors.

[0022] like Figures 1 to 5As shown in the figure, an embodiment of the present invention provides an automated assembly line for testing the electrical performance of a single-phase reactor, used for performance testing of a single-phase reactor product 100. The production line includes a clamping area 2, a waiting area 3, a testing area, an inspection area, an unloading area, a fixture plate 11, and a high-speed conveyor chain. The clamping area 2, waiting area 3, testing area, inspection area, and unloading area are sequentially arranged along the conveying direction of the high-speed conveyor chain. The high-speed conveyor chain is used for conveying the fixture plate 11, realizing the orderly conveying of the fixture plate 11 and the single-phase reactor product 100 between each area, providing basic support for the automated operation of the production line. The clamping area 2 is used to receive the fixture plate 11 and load the single-phase reactor product 100. The single-phase reactor product 100 is clamped onto the fixture plate 11 according to a preset posture; the waiting area 3 is used to receive and temporarily store the fixture plate 11 from the clamping area 2; the testing area is used to receive the fixture plate 11 from the waiting area 3 and perform electrical performance and functional tests on the single-phase reactor product 100 on the fixture plate 11; the inspection area is used to receive the fixture plate 11 from the testing area and perform appearance inspection on the single-phase reactor product 100 on the fixture plate 11; the offline area is used to receive the fixture plate 11 from the inspection area and remove the single-phase reactor product 100 from the fixture plate 11; the testing area is equipped with a product posture adjustment device, which is used to adjust the posture of the single-phase reactor product 100 on the fixture plate 11.

[0023] in, Figure 15 A structural schematic diagram of the single-phase reactor product 100 is provided, which is equipped with fitting 1 74, fitting 2 75 and temperature-controlled lead 76.

[0024] In this automated single-phase reactor electrical performance testing assembly line, the core functions and specific operating methods of each area are as follows: Clamping area 2 serves as the starting station of the production line, primarily used to receive the jig plate 11 from the transmission line. Operators clamp the single-phase reactor product 100 onto the jig plate 11 according to a preset posture, ensuring the product's stable position during subsequent testing and inspection, and preventing posture deviation from affecting testing accuracy and results. After clamping, the operator starts the production line, and the jig plate 11, carrying the single-phase reactor product 100, enters the next station driven by the transmission double-speed chain. Waiting area 3 receives and temporarily stores the jig plate 11 from clamping area 2. Its core function is to buffer and coordinate the production cycle. Waiting area 3 waits in real-time for the response signal from the testing area. Only after confirming that the testing area station is zeroed out and there is no material accumulation will the jig plate 11 be released, ensuring that the testing area can receive the products to be tested in an orderly and efficient manner, avoiding station congestion or testing interruptions, and guaranteeing the smooth operation of the entire production line. The testing area, as a functional area of ​​this production line, is used to receive the jig plate 11 from the waiting area 3 and to conduct comprehensive electrical performance tests on the single-phase reactor product 100 on the jig plate 11 to ensure that the product's electrical performance parameters meet the factory standards. The testing area also includes a product posture adjustment device, which is used to precisely adjust the posture of the single-phase reactor product 100 on the jig plate 11, solving the posture deviation problem that may occur during clamping, ensuring precise alignment of the test probe, fixture, and product test points, improving the accuracy and reliability of electrical performance testing, and avoiding problems such as distorted test data and misjudgment of test results due to posture deviation.

[0025] The inspection area receives the fixture plate 11 from the testing area and performs visual inspection on the single-phase reactor products 100 on the fixture plate 11. This compensates for the limitations of electrical performance testing and enables comprehensive control over product quality. Visual inspection mainly targets defects such as scratches, deformation, damage, and stains on the product surface, as well as the proper installation of product components. This ensures that the product not only meets electrical performance standards but also its appearance quality meets factory requirements, improving the overall product quality. The off-line area, as the end station of the production line, receives the fixture plate 11 from the inspection area and removes the single-phase reactor products 100 from it. For products that pass testing and inspection, operators remove them from the fixture plate 11, completing the finished product off-line process. For unqualified products, operators affix unqualified labels and manually remove them from the line, ensuring that unqualified products do not flow into subsequent stages. After off-line completion, the fixture plate 11 will enter the subsequent recycling stage for reuse, reducing production costs.

[0026] In practical applications, the transmission speed-multiplying chain can adopt a wear-resistant and high-temperature-resistant conveying structure. Its conveying speed can be flexibly adjusted according to production needs, adapting to the testing cycle of single-phase reactor products of different specifications. The fixture plate 11 is made of high-strength materials with excellent insulation properties, which can stably support the single-phase reactor product 100 while avoiding interference with the product's electrical performance testing. The product posture adjustment device can achieve multi-directional, high-precision posture adjustment according to the structural characteristics of different product specifications, adapting to diverse product testing needs without frequent fixture changes, thus improving the versatility and adaptability of the production line.

[0027] This application utilizes a transmission speed-doubling chain to achieve orderly connection between various workstations, ensures testing accuracy through a product posture adjustment device, and concentrates manual operations on simple processes such as clamping and unloading, significantly reducing manual involvement in the testing process. In particular, it avoids manually plugging and unplugging high-voltage and high-current test cables, fundamentally reducing safety hazards. At the same time, it shortens the testing cycle, improves production efficiency, and meets the needs of large-scale production.

[0028] The working principle of this application embodiment is as follows: The production line connects various functional areas through a transmission double-speed chain to realize the automated flow of the jig plate 11 and the single-phase reactor product 100. The core is to complete the entire process of product clamping, testing, inspection and off-line through the joint operation of each area, while ensuring the accuracy of testing with the help of the product posture adjustment device. Specifically: First, the fixture plate 11 is conveyed to the clamping area 2, where the operator clamps the single-phase reactor product 100 onto the fixture plate 11 in a preset posture. After clamping, the fixture plate 11 is temporarily stored in the waiting area 3 under the drive of the transmission double-speed chain, awaiting the response from the testing area. Once the testing area is ready, the fixture plate 11 flows into the testing area, where the product posture adjustment device precisely adjusts the product posture to ensure accurate alignment of the test points. Subsequently, the testing area performs electrical performance and functional tests on the product. After the test, the fixture plate 11 flows into the inspection area, where staff perform visual inspection of the product to determine if it is qualified. Qualified products enter the offline area to complete the offline process, while unqualified products are labeled and manually removed from the offline process. After offline processing, the fixture plate 11 enters the return process and is reused. Compared to the manual or semi-automated operation modes in existing technologies, this production line significantly improves testing efficiency, reduces the labor intensity of operators, and eliminates the safety hazards caused by high-voltage and high-current testing through automated flow, precise posture adjustment, and zoned collaborative operation. At the same time, through full-process quality control, it improves the product qualification rate and can well meet the needs of large-scale production of single-phase reactors.

[0029] like Figures 1 to 2As shown, in some embodiments of the present invention, the single-phase reactor electrical performance automatic test finished product assembly production line further includes: a feeding carrier elevator 1, located at the inlet end of the clamping area 2, for conveying the jig plate 11 to the clamping area 2; a discharging carrier elevator 9, located at the outlet end of the offline area, for receiving the jig plate 11 from the offline area; and a jig plate return line 10, for conveying the jig plate 11 from the discharging carrier elevator 9 to the feeding carrier elevator 1, forming a circulating system for the jig plate 11.

[0030] Specifically, both the feeding carrier elevator 1 and the discharging carrier elevator 9 are conveying equipment with lifting adjustment functions. They can adopt chain-type or hydraulic lifting structures, and their lifting height can be flexibly adjusted according to the installation height of the transmission double-speed chain and the fixture plate return line 10 to meet the height connection requirements of each station in the production line. The fixture plate return line 10 adopts a conveying structure that is compatible with the transmission double-speed chain. It can be selected as a chain plate type or roller type conveyor. Its conveying speed is matched with the transmission double-speed chain to ensure the smooth circulation of the fixture plate 11. The core function of the feeding carrier elevator 1 is to receive the empty jig plate 11 from the jig plate return line 10 and accurately transport it to the inlet end of the clamping area 2 to realize the orderly feeding of the jig plate 11; the discharging carrier elevator 9 is used to receive the empty jig plate 11 from the offline area and transport it to the inlet end of the jig plate return line 10; the jig plate return line 10 is responsible for transporting the empty jig plate 11 from the discharging carrier elevator 9 back to the feeding carrier elevator 1 to complete the recycling of the jig plate 11.

[0031] The feeding carrier elevator 1 enables automated feeding of empty fixture plates 11 from the return line to the clamping area 2, eliminating the need for manual handling and reducing the labor intensity of operators. At the same time, it ensures that the fixture plates 11 are accurately aligned with the clamping area 2, avoiding congestion at the clamping station. The unloading carrier elevator 9 enables automated receiving and lifting of empty fixture plates 11 after they have come off the production line, connecting the off-line area and the fixture plate return line 10, ensuring that the empty fixture plates 11 can quickly leave the off-line area, freeing up space for subsequent products to come off the production line. The fixture plate return line 10 enables the empty fixture plates 11 to automatically return from the end of the production line to the beginning, eliminating the need for manual transfer and significantly improving the turnover efficiency of the fixture plates 11.

[0032] like Figures 3 to 4 As shown, in some embodiments of the present invention, the clamping area 2 includes a barcode scanning camera 12 and a camera bracket 13; the barcode scanning camera 12 is used to read the identification code on the fixture plate 11; the camera bracket 13 is used to install the barcode scanning camera 12, and the camera bracket 13 is also used to adjust the installation height and installation angle of the barcode scanning camera 12.

[0033] Specifically, the barcode scanner 12 is an optoelectronic device with image acquisition and barcode recognition functions. It can be a high-definition industrial barcode scanner, capable of quickly recognizing various barcodes such as QR codes and barcodes affixed to the fixture plate 11. Its recognition speed is fast and its accuracy is high, making it suitable for continuous production line operation. The camera bracket 13 has multi-axis freedom, allowing adjustment of the installation height and angle of the barcode scanner 12. Specifically, it can be flexibly adjusted according to the affixing position of the barcode on the fixture plate 11 and the conveying height of the fixture plate 11. The barcode scanner 12 is used to read the barcode on the fixture plate 11, obtaining the identification information of the fixture plate 11, enabling traceability and management of the fixture plate 11 and the corresponding single-phase reactor product 100. The camera bracket 13 provides a stable mounting platform for the barcode scanner 12 and, through height and angle adjustments, ensures that the barcode scanner 12 is always in the optimal recognition position, guaranteeing the stability and accuracy of barcode reading.

[0034] like Figures 3 to 6 As shown, in some embodiments of the present invention, the jig plate 11 includes: a jig main support plate 18; a product support plate 21, which is disposed above the jig main support plate 18 at intervals via insulating support plates 23; a product limiting plate 22, which is detachably adsorbed onto the product support plate 21 and is used to limit the position of the single-phase reactor product 100; and a temperature switch clamping bracket 25, which is disposed on the product support plate 21 on the side near the insulating support plate 23, and the temperature switch clamping bracket 25 is provided with a temperature switch lead clamp 24, which is used to clamp the temperature switch lead of the single-phase reactor product 100. The product support plate 21 is also provided with a retaining edge 20, which is used to laterally limit the single-phase reactor product 100; the main support plate 18 of the fixture is provided with a buffer strip 16 around its perimeter, the top surface of the main support plate 18 of the fixture is provided with an identification code affixing area 17, and the top edge of the main support plate 18 of the fixture is also provided with a handle 19.

[0035] Specifically, the main support plate 18 of the fixture supports all components and the single-phase reactor product 100 on it, ensuring the overall structural stability of the fixture plate 11 and adapting to the continuous conveying and testing conditions of the production line. The product support plate 21 is installed above the main support plate 18 at intervals via insulating support plates 23. The insulating support plates 23 are made of high-strength insulating material, and their core function is to achieve electrical isolation between the product support plate 21 and the main support plate 18, preventing current conduction to the fixture body during testing and affecting the accuracy of test data, while also preventing potential leakage. The product limiting plate 22 is detachably fixed to the product support plate 21 using magnetic adsorption. It can be flexibly replaced according to the structural dimensions of different specifications of the single-phase reactor product 100, precisely limiting the placement position of the product on the product support plate 21 to prevent displacement of the product during conveying and testing.

[0036] The temperature switch uses a clamping bracket 25 to fix the temperature switch lead clamp 24. The temperature switch lead clamp 24 is made of a material with excellent conductivity and a certain clamping force. It is used to stably clamp the temperature switch lead of the single-phase reactor product 100, ensuring that the temperature switch lead is accurately connected to the test component during the test, and ensuring the smooth progress of the electrical performance test of the temperature switch. The edge guard 20 of the product support plate 21 is used to laterally limit the single-phase reactor product 100. Together with the product limit plate 22, it realizes the all-round positioning of the product and further improves the stability of the product clamping. The buffer strips 16 around the main support plate 18 of the fixture are made of elastic and wear-resistant material, which can buffer the collision between the fixture plate 11 and the equipment and other fixture plates during the conveying and transfer process, and avoid damage to the fixture plate 11 and the product; the identification code affixing area 17 is used to affix the unique identification code of the fixture plate 11, which, together with the barcode scanning camera 12 in the clamping area 2, realizes the traceability management of the fixture plate and the corresponding product; the handle 19 makes it convenient for operators to manually move the fixture plate 11 in special circumstances such as equipment failure, improving the convenience of operation.

[0037] More specifically, the detachable adsorption design of the product limiting plate 22 allows the fixture plate 11 to be adapted to single-phase reactor products 100 of different specifications without replacing the entire fixture plate, thus reducing equipment investment costs; the setting of the insulating support plate 23 achieves electrical isolation, avoids interference from test current, improves the accuracy of electrical performance testing, and ensures operational safety; the cooperation between the temperature switch lead clamp 24 and the temperature switch clamp placement rack 25 ensures stable clamping of the temperature switch lead, avoiding test interruption or data distortion due to poor contact during testing.

[0038] like Figures 1 to 2 , Figures 7 to 8 As shown, in some embodiments of the present invention, the test area includes an automatic tester 4 and an automatic tester 5 arranged sequentially along the conveying direction. The automatic tester 4 and the automatic tester 5 are respectively used to perform unloaded testing and loaded testing on the product. Both the automatic tester 4 and the automatic tester 5 include a tester body 26, and two product posture adjustment devices are provided. The two product posture adjustment devices are respectively located in the two tester bodies 26. The attitude adjustment device includes: a product-carrying fixture 28 for positioning the jig plate 11 at the test position; an internal moving clamp 27 for gripping and adjusting the position of the single-phase reactor product 100 on the jig plate 11; a jig plate positioning device 29 for lifting the jig plate 11 away from the transmission speed chain; and a blocking mechanism 30 for preventing the jig plate 11 from moving before it reaches the test position.

[0039] Specifically, both Automatic Tester 1 (4) and Automatic Tester 2 (5) are automated devices with precise electrical performance testing capabilities. Their structures are compatible and they work collaboratively, each undertaking different types of electrical performance testing tasks: Automatic Tester 1 (4) primarily performs unloaded tests, including testing core electrical performance parameters such as withstand voltage, insulation resistance, DC resistance, and inductance, without requiring a large current to be applied to the product, focusing on verifying the product's basic electrical performance compliance; Automatic Tester 2 (5) primarily performs loaded tests, capable of applying a maximum current of approximately 1000A to the product, testing the stability and reliability of the product's electrical performance under actual working loads. The main body of the tester (26), serving as the mounting carrier for the automatic testers, integrates core components such as test circuits and control modules, providing a stable operating environment for the testing work.

[0040] The components of the attitude adjustment device have clearly defined functions and work together in a coordinated manner: the product-bearing fixture 28 adopts a rigid positioning structure to accurately position the jig plate 11 inside the main body 26 of the testing machine at the preset test position, preventing displacement of the jig plate 11 and laying the foundation for subsequent attitude adjustment and testing operations; the internal moving clamp 27 has multi-directional movement and gripping functions, which can accurately grip the single-phase reactor product 100 on the jig plate 11 and adjust the product's attitude according to testing requirements to ensure that the product test point is accurately aligned with the test probe and clamp, solving the clamping process problem. To prevent potential posture deviations during transport, the carrier plate positioning device 29 adopts a lifting structure. Its core function is to lift the fixture plate 11 off the conveyor chain, detaching it from the transport structure and avoiding vibration or displacement during transport that could affect test accuracy. The blocking mechanism 30 adopts a cylinder-driven blocking structure to prevent the fixture plate 11 from moving before it reaches the preset test position, ensuring that the fixture plate 11 can accurately stop at the test position, avoiding positioning deviations caused by transport inertia, and preventing multiple fixture plates 11 from entering the test area simultaneously and causing congestion.

[0041] Separating unloaded and loaded tests avoids interference from the high current and heat generated during loaded testing on unloaded test data, improving the accuracy and reliability of both types of tests. At the same time, setting up two separate automatic testing machines enables parallel connection of testing processes, shortens the testing cycle of a single product, improves the overall testing efficiency of the production line, and adapts to the needs of large-scale production.

The vertical moving guide rail 31 is used for the fixture assembly 33 and the temperature opening test fixture 34 to move along the first direction, and the horizontal moving guide rail 35 is used for the fixture assembly 33 and the temperature opening test fixture 34 to move along the second direction; the main body 26 of the testing machine is also equipped with an electric cylinder, which is used to push the moving fixture main body frame 32 to move along the third direction.

[0043] The first direction is the vertical direction, specifically the height direction of the main frame 32 of the mobile fixture; the second direction is the horizontal direction, specifically the length direction of the main frame 32 of the mobile fixture; more specifically, the second direction is perpendicular to the conveying direction of the transmission speed-boosting chain; the third direction is the width direction of the main frame 32 of the mobile fixture, and the third direction is perpendicular to the second direction.

[0044] Specifically, the main frame 32 of the moving fixture adopts a high-strength rigid metal structure, which serves as the main mounting carrier of the internal moving fixture 27. It is used to fix components such as the vertical moving guide rail 31 and the horizontal moving guide rail 35, ensuring the overall structural stability of the internal moving fixture 27. It can withstand the forces during the movement of the fixture and the clamping of the product, and avoid affecting the moving accuracy and clamping stability due to structural deformation.

[0045] Both the vertical moving guide rail 31 and the horizontal moving guide rail 35 are high-precision linear guide rails, featuring smooth movement, accurate positioning, and minimal wear. They are arranged perpendicularly to each other, forming a two-dimensional moving guide structure: the vertical moving guide rail 31 is used for the fixture assembly 33 and the temperature opening test fixture 34 to move along a first direction, achieving precise vertical alignment between the fixture and the product test point; the horizontal moving guide rail 35 is used for the fixture assembly 33 and the temperature opening test fixture 34 to move horizontally along a second direction, achieving position adjustment of the fixture on the horizontal plane to accommodate differences in test point positions for different product specifications. More specifically, there are two sets of vertical moving guide rails 31, arranged opposite each other. Similarly, there are two sets of horizontal moving guide rails 35, designated as group A and group B. Group A is located below the main frame 32 of the moving fixture, and group B is located above the main frame 32 of the moving fixture. A slider is provided on the vertical moving guide rail 31 to support group A.

[0046] The clamp assembly 33 is used to clamp the hardware of the single-phase reactor product 100, providing a stable electrical connection for the product's electrical performance testing, ensuring smooth transmission of test current and signals, and guaranteeing the smooth conduction of electrical performance tests such as withstand voltage and inductance. The temperature switch test clamp 34 adopts a special clamping structure adapted to the temperature switch, with precise clamping and conductivity functions, and is used to clamp the temperature switch of the single-phase reactor product 100 to realize the detection of the electrical performance parameters related to the temperature switch, ensuring that the product's temperature protection function meets the standards. The electric cylinder inside the main body 26 of the testing machine adopts a high-precision drive structure, with stable thrust and precise movement. Its core function is to push the moving clamp main frame 32 to move in a direction perpendicular to both the vertical and horizontal directions, driving the entire internal moving clamp 27 to approach or move away from the product on the fixture plate 11, realizing precise docking and separation of the clamp and the product, and avoiding collision damage between the clamp and the product.

[0047] like Figures 7 to 15 As shown, in some embodiments of the present invention, the fixture assembly 33 includes a fixture space moving device 36, a cylinder attitude adjusting device 37, and a cylinder clamping device 38. The fixture space moving device 36 includes a horizontal slider 50, a second vertical moving slide rail 51, and a front-back moving slide rail 53. The horizontal slider 50 is disposed on the horizontal moving guide rail 35, the second vertical moving slide rail 51 is disposed on the horizontal slider 50, and the front-back moving slide rail 53 is disposed on the second vertical moving slide rail 51. The cylinder attitude adjustment device 37 includes a first vertical sliding rail 45, a rotating plate 46, a first connecting plate 47, and a second connecting plate 48; one side of the second connecting plate 48 is connected to the front and rear sliding rail 53, and the other side of the second connecting plate 48 is connected to the first vertical sliding rail 45; the rotating plate 46 is disposed on the first vertical sliding rail 45, and the first vertical sliding rail 45 is used for the movement of the rotating plate 46; one side of the first connecting plate 47 is connected to the rotating plate 46, and the other side of the first connecting plate 47 is connected to the cylinder clamping device 38. The cylinder clamping device 38 includes a clamping cylinder connecting plate 39, an insulating pad 40, an upper clamping copper block 41, a clamping cylinder 42, a lower clamping copper block 43, and a main fixing plate 44. The clamping cylinder 42 is used to drive the clamping cylinder connecting plate 39 to move. The mounting end of the clamping cylinder 42 and the lower clamping copper block 43 are both located on the main fixing plate 44, which is located on the first connecting plate 47. The insulating pad 40 is located on the clamping cylinder connecting plate 39, and one end of the insulating pad 40 away from the clamping cylinder connecting plate 39 is connected to the upper clamping copper block 41. The upper pressing copper block 41 is used to supply power to the single-phase reactor product 100.

[0048] Specifically, the fixture space moving device 36 serves as the moving basis for the fixture assembly 33, enabling multi-directional precise movement of the cylinder attitude adjustment device 37 and the cylinder clamping device 38. Its horizontal slider 50 is mounted on the horizontal moving guide rail 35, allowing it to slide horizontally along the guide rail and drive the entire fixture assembly 33 to achieve horizontal position adjustment. The second vertical moving slide rail 51 is mounted on the horizontal slider 50, enabling minute vertical movements of the front and rear moving slide rails 53 and subsequent components to accommodate height differences in the product fittings. The front and rear moving slide rails 53 are mounted on the second vertical moving slide rail 51, enabling the cylinder attitude adjustment device 37 and the cylinder clamping device 38 to move along the length of the front and rear moving slide rails 53, ensuring precise docking with the product fittings. These three components work together to form a three-dimensional moving structure, further improving the moving accuracy and adaptability of the fixture assembly 33.

[0049] The cylinder attitude adjustment device 37 is used to fine-tune the attitude of the cylinder clamping device 38 to ensure that the upper clamping copper block 41 and the lower clamping copper block 43 are precisely fitted with the product hardware. Its second connecting plate 48 is connected to the front and rear moving slide rail 53 on one side and to the first up and down moving slide rail 45 on the other side to achieve a stable connection with the clamping space moving device 36. The first up and down moving slide rail 45 is used to move the rotating plate 46 up and down to further fine-tune the height of the clamping device. The rotating plate 46 can rotate around its own axis to adjust the angle of the cylinder clamping device 38 to adapt to the installation attitude of the product hardware. The first connecting plate 47 is connected to the rotating plate 46 on one side and to the cylinder clamping device 38 on the other side, which plays the role of fixing and transmitting force to ensure structural stability during attitude adjustment.

[0050] The cylinder clamping device 38 is the clamping and power supply component of the fixture assembly 33. Its main fixing plate 44 is located on the first connecting plate 47 and serves as the mounting carrier for the cylinder clamping device 38, used to fix the clamping cylinder 42 and the lower clamping copper block 43. The clamping cylinder 42 serves as the driving component, used to drive the clamping cylinder connecting plate 39 to move up and down, thereby moving the upper clamping copper block 41 closer to or away from the lower clamping copper block 43, realizing the clamping and loosening of the product hardware. The insulating pad 40 is located between the clamping cylinder connecting plate 39 and the upper clamping copper block 41 to achieve electrical isolation and prevent current from being conducted to the clamping cylinder 42 and other components, affecting test safety and data accuracy. The upper clamping copper block 41 and the lower clamping copper block 43 are made of copper with excellent conductivity. The two work together to clamp the product hardware. The upper clamping copper block 41 is used to supply power to the single-phase reactor product 100, ensuring smooth transmission of test current and ensuring the smooth progress of electrical performance testing.

[0051] In detail, the three-dimensional moving structure of the fixture space moving device 36, in conjunction with the overall movement of the internal moving fixture 27, achieves multi-dimensional precise positioning of the fixture assembly 33. It can flexibly adapt to product fittings of different specifications and postures, eliminating the need for frequent adjustments to the overall fixture position and improving testing efficiency. The angle and height fine-tuning function of the cylinder posture adjustment device 37 can effectively compensate for minor posture deviations generated during clamping and overall movement, ensuring a perfect fit between the clamping device and the product fittings and avoiding test data distortion due to contact deviations.

[0052] Furthermore, the insulating pad 40 in the cylinder clamping device 38 achieves electrical isolation between the clamping components and the driving components, ensuring the safety of the testing process, avoiding current interference, and improving the accuracy of the test data. The copper material design of the upper clamping copper block 41 and the lower clamping copper block 43 ensures excellent conductivity and a certain degree of wear resistance, extending the service life of the fixture. The precise drive of the clamping cylinder 42 achieves stable clamping of the product hardware, avoiding poor contact due to loose clamping during the test, and ensuring continuous and stable testing.

[0053] like Figures 7 to 15 As shown, in some embodiments of the present invention, a first locking block 49 is also provided on the horizontal slider 50, and the first locking block 49 is used to lock the horizontal slider 50 onto the horizontal moving guide rail 35. The front-to-back sliding rail 53 is connected to the second up-and-down sliding rail 51 by a connecting slider.

[0054] More specifically, the connecting slider is provided with a second locking block 52 and a third locking block 54, wherein the second locking block 52 is used to lock the connecting slider onto the front and rear moving slide rail 53, and the third locking block 54 is used to lock the connecting slider onto the second up and down moving slide rail 51.

[0055] Specifically, the first locking block 49 can adopt a threaded locking structure, adapted to the structural dimensions of the horizontal slider 50 and the horizontal moving guide rail 35. Its core function is to lock the horizontal slider 50 onto the horizontal moving guide rail 35. When the horizontal slider 50 moves along the horizontal moving guide rail 35 to the preset position, tightening the locking bolt of the first locking block 49 makes the first locking block 49 and the horizontal moving guide rail 35 fit tightly together, generating sufficient friction to limit the displacement of the horizontal slider 50 and ensure the positioning accuracy in the horizontal direction.

[0056] The connecting slider can adopt a high-strength rigid structure to connect the front-to-back moving slide rail 53 and the second up-and-down moving slide rail 51, enabling them to work together to drive the subsequent cylinder attitude adjustment device 37 and cylinder clamping device 38 to move, ensuring the continuity of the three-dimensional moving structure. Specifically, the front-to-back moving slide rail 53 and the second up-and-down moving slide rail 51 are perpendicular to each other and can be installed on two adjacent sides of the cube-shaped connecting slider, and their installation positions on the connecting slider do not interfere with each other.

[0057] Both the second locking block 52 and the third locking block 54 can adopt a threaded locking design that is compatible with the structure of the first locking block 49, and are used to lock and fix the connecting slider to the front and rear moving slide rail 53 and the second up and down moving slide rail 51 respectively. The third locking block 54 is used to lock the connecting slider onto the second up-down sliding rail 51. When the connecting slider drives the front and rear sliding rails 53 and subsequent components to move to a preset height on the second up-down sliding rail 51, tightening the third locking block 54 can limit the relative position between the connecting slider and the second up-down sliding rail 51.

[0058] The second locking block 52 is used to lock the connecting slider onto the front and rear moving slide rail 53. When the connecting slider moves along the front and rear moving slide rail 53 to the preset position, tightening the second locking block 52 will fix the connecting slider onto the front and rear moving slide rail 53 and prevent displacement after adjustment.

[0059] The connecting slider ensures a stable connection between the front and rear moving slide rail 53 and the second upper and lower moving slide rail 51, guaranteeing smooth coordinated movement and preventing jamming or offset during movement, thus ensuring the stability of the three-dimensional moving structure. The locking blocks enable precise locking of the fixture space moving device 36 in three spatial directions. When the fixture assembly 33 moves to the preset test position, locking the locking blocks completely restricts the displacement of the fixture assembly 33, ensuring it maintains a fixed posture during testing and preventing fixture offset due to vibration or force during testing. This also ensures stable contact between the upper and lower pressing copper blocks 41 and the product fittings, as well as the continuity of power supply.

[0060] like Figures 7 to 15 As shown, in some embodiments of the present invention, the temperature-controlled test fixture 34 includes: a test probe 55 for contacting the temperature-controlled lead of the single-phase reactor product 100; an insulating base 56 for supporting the test probe 55; a slide cylinder 57 for driving the insulating base 56 to move; a temperature-controlled fixture slider 59 mounted on a horizontal moving guide rail 35 for supporting the slide cylinder 57; and a slide rail locking plate 58 for locking the temperature-controlled fixture slider 59 on the horizontal moving guide rail 35.

[0061] Specifically, both the vertical moving guide rail 31 and the horizontal moving guide rail 35 adopt high-precision linear guide rails, which have the characteristics of smooth movement, accurate positioning, and low wear. They are arranged perpendicularly to each other to form a two-dimensional moving guide structure: the vertical moving guide rail 31 is used for the fixture assembly 33 and the temperature opening test fixture 34 to move along the first direction, so as to achieve precise docking of the fixture and the product test point in the height direction; the horizontal moving guide rail 35 is used for the fixture assembly 33 and the temperature opening test fixture 34 to move horizontally along the second direction, so as to achieve the position adjustment of the fixture on the horizontal plane and adapt to the position differences of the test point of different product specifications. More specifically, there are two sets of vertical moving guide rails 31, which are arranged opposite each other. There are also two sets of horizontal moving guide rails 35, which are designated as group A and group B. Group A is located at the lower part of the main frame 32 of the moving fixture, and group B is located at the upper part of the main frame 32 of the moving fixture. A slider is provided on the vertical moving guide rail 31, which is used to support group A. The temperature opening fixture slider 59 is installed on group B. In addition, the temperature opening test fixture 34 also includes a slide rail locking plate 58 for locking the temperature opening fixture slider 59 on group B.

[0062] The test probe 55 can be made of a metal probe structure with excellent conductivity and wear resistance. Its head is designed with a smooth arc shape, which can ensure good contact with the temperature switch lead, realize smooth transmission of test signals and current, and avoid scratching the temperature switch lead, thus protecting the product component. The insulating base 56 is made of high-strength insulating material and serves as the mounting carrier for the test probe 55. Its core function is to achieve electrical isolation between the test probe 55 and other metal components, prevent test current from being conducted to components such as the slide cylinder 57 and the temperature switch clamp slider 59, prevent current interference from affecting the accuracy of test data, and ensure operational safety during the test process. The slide cylinder 57 adopts a high-precision linear slide drive structure, which features smooth movement, accurate positioning, and rapid response. Its output end is connected to the insulating base 56 and is used to drive the insulating base 56 and the test probe 55 to move in a preset direction, realizing precise docking and separation of the test probe 55 and the temperature switch lead, ensuring tight contact while avoiding excessive compression that could damage the temperature switch lead. The temperature-controlled fixture slider 59 adopts a rigid slider structure adapted to the horizontal moving guide rail 35. It is mounted on the horizontal moving guide rail 35 and can slide flexibly along it. It supports the slide cylinder 57, the insulating base 56, and the test probe 55, driving the entire temperature-controlled test fixture 34 to achieve horizontal position adjustment, adapting to the positional differences of temperature-controlled leads of different product specifications. The slide rail locking plate 58 can adopt a threaded locking structure, adapted to the structural dimensions of the temperature-controlled fixture slider 59 and the horizontal moving guide rail 35, and is used to lock the temperature-controlled fixture slider 59 in a preset position on the horizontal moving guide rail 35. When the temperature-controlled fixture slider 59 moves along the horizontal moving guide rail 35 to the position of the temperature-controlled lead wire of the product, the locking bolts of the slide rail locking plate 58 are tightened to make the slide rail locking plate 58 fit tightly with the horizontal moving guide rail 35, generating sufficient friction to limit the displacement of the temperature-controlled fixture slider 59, ensuring that the temperature-controlled test fixture 34 remains in a fixed position during the test, and avoiding poor contact between the test probe 55 and the temperature-controlled lead wire due to vibration or force.

[0063] like Figures 7 to 15 As shown, in some embodiments of the present invention, the carrier plate positioning device 29 includes: a third connecting plate 64 disposed on the transmission speed-multiplying chain; a lifting cylinder fixing plate 63 connected to the third connecting plate 64 via a support column; a carrier lifting positioning plate 60 for supporting the main support plate 18 of the fixture plate 11, on which a test notch is provided; an insulation test auxiliary fixture 61 embedded in the test notch on the carrier lifting positioning plate 60; and a first lifting cylinder 62 mounted on the lifting cylinder fixing plate 63, with its piston rod connected to the carrier lifting positioning plate 60.

[0064] Specifically, the third connecting plate 64 can be manually positioned at the corresponding location on the transmission speed chain to achieve a stable connection with it, providing a stable installation foundation for the entire carrier plate positioning device 29 and ensuring that the device will not shift or shake during operation. The support column adopts a high-strength metal cylindrical structure, with its two ends fixedly connected to the third connecting plate 64 and the lifting cylinder fixing plate 63, respectively. The lifting cylinder fixing plate 63 adopts a rigid flat plate structure and is used to install and fix the first lifting cylinder 62. Its structural dimensions are adapted to the installation requirements of the first lifting cylinder 62, ensuring that the first lifting cylinder 62 can be stably installed, preventing the cylinder from shifting or loosening during the lifting process, and ensuring the stability and accuracy of the lifting action. The first lifting cylinder 62 adopts a high-precision lifting cylinder structure, featuring stable thrust, accurate lifting height, and rapid response. Its piston rod is fixedly connected to the carrier lifting positioning plate 60. Its core function is to drive the carrier lifting positioning plate 60 to move up and down, thereby lifting or lowering the fixture plate 11 from the transmission speed chain, realizing the separation and connection of the fixture plate 11 and the transmission speed chain. The carrier lifting positioning plate 60 can adopt a rigid flat plate structure adapted to the structure of the fixture main support plate 18. Its top surface is flat and smooth, used to accurately support the fixture main support plate 18 of the fixture plate 11, ensuring that the fixture plate 11 can remain horizontal and stable after being lifted, avoiding tilting or displacement. The test notch opened on it is used to embed the insulation test auxiliary fixture 61, providing a precise installation position for the insulation test auxiliary fixture 61. The insulation test auxiliary fixture 61 is used for electrical isolation between the fixture plate 11 and the carrier lifting and positioning plate 60, to prevent current from being conducted to the carrier plate positioning device 29 and the transmission speed doubler chain during the test, to prevent current interference from affecting the accuracy of test data, and to ensure the operational safety of the test process.

[0065] like Figures 1 to 2 As shown, in some embodiments of the present invention, the inspection area includes an appearance inspection area 6 and an appearance inspection area 7. The appearance inspection area 6 and the appearance inspection area 7 are respectively used for automatic appearance inspection and manual appearance inspection of the single-phase reactor product 100. The appearance inspection area 27 is equipped with a manual rotation device, which is used to support the fixture plate 11 and rotate the fixture plate 11 to inspect the appearance of the single-phase reactor product 100 around its perimeter.

[0066] Specifically, appearance inspection area 6 and appearance inspection area 7 are sequentially arranged along the conveying direction of the double-speed conveyor chain, receiving the fixture plate 11 and single-phase reactor product 100 from the test area. They respectively undertake both automatic and manual appearance inspection tasks, forming a dual inspection mode of automatic initial inspection and manual re-inspection. Among them, appearance inspection area 6 serves as an automatic appearance inspection station, integrating a high-definition industrial camera, an image recognition system, and a light source supplementary lighting device. The high-definition industrial camera is used to acquire appearance images of the single-phase reactor product 100, the light source supplementary lighting device is used to provide a uniform and stable lighting environment to avoid missed or false judgments caused by uneven light levels, and the image recognition system is used to perform real-time analysis and comparison of the acquired images to automatically identify whether there are common appearance defects such as scratches, deformation, damage, and stains on the product surface, as well as whether the product components are installed correctly.

[0067] The appearance inspection area 27 serves as a manual appearance inspection station, used to re-inspect products that have passed the automatic appearance inspection, and to check for defects that may be missed during the automatic inspection process, further improving the accuracy of appearance inspection. The manual rotation device inside adopts a rigid load-bearing structure and is adapted to the structural dimensions of the fixture plate 11. Its core function is to support the fixture plate 11 and can be flexibly rotated under the operation of the operator, so as to comprehensively observe the four sides and corners of the product, ensuring that no appearance defects are missed, especially for corners, gaps and other areas that are difficult to cover by automatic inspection, to achieve accurate inspection.

[0068] like Figures 10 to 15 As shown, in some embodiments of the present invention, the manual rotation device includes a carrier lifting and positioning plate 65, a photoelectric switch assembly 66, a rotation limit assembly 67, a lifting cylinder 68, a main structure 69, a rotary bearing 70, a rotation mechanism 71, a bearing limit sleeve 72, and a spring pin assembly 73. This manual rotation device is installed on a high-speed chain conveyor line, and the various components work together to achieve precise positioning, lifting, rotation, and reset of the fixture plate 11. It provides a convenient and stable operating platform for operators to comprehensively inspect the appearance of the single-phase reactor product 100, further improving the efficiency and comprehensiveness of manual appearance inspection.

[0069] Specifically, the main structure 69 is used to fix all components such as the lifting cylinder 68, the rotary bearing 70, and the bearing limit sleeve 72, ensuring the overall stability of the manual rotation device and enabling it to withstand the weight of the jig plate 11 and the product. This prevents structural deformation or shaking during lifting and rotation, ensuring operational safety and stability. The lifting cylinder 68 adopts a high-precision lifting cylinder structure and is installed on the main structure 69. Its piston rod is fixedly connected to the carrier lifting positioning plate 65, which is used to drive the carrier lifting positioning plate 65 to move up and down, thereby lifting and lowering the jig plate 11. The lifting and positioning plate 65 of the vehicle adopts a rigid flat plate structure adapted to the structure of the jig plate 11. Its top surface has a limiting structure corresponding to the jig plate 11, used to precisely limit the jig plate 11 and prevent displacement during lifting and rotation. Its core function is to rise under the drive of the lifting cylinder 68, limit the jig plate 11 on the double-speed chain, and then lift it up, completely disengaging the jig plate 11 from the double-speed chain, providing uninterrupted space for subsequent rotation operations. The rotary bearing 70 is embedded in the top of the main structure 69, and works with the bearing limiting sleeve 72 to achieve fixation and limiting. The bearing limiting sleeve 72 is used to limit the displacement of the rotary bearing 70, ensuring that the rotary bearing 70 is securely installed and rotates smoothly, avoiding deviation or jamming during rotation.

[0070] The rotating mechanism 71 is mounted on the rotary bearing 70 and works in conjunction with the lifting and positioning plate 65 of the carrier. When the jig plate 11 is lifted, the operator can manually rotate the jig plate 11, causing the rotating mechanism 71 to rotate synchronously along the rotary bearing 70, thereby rotating the single-phase reactor product 100. This allows the operator to fully observe the appearance of the product from all sides. The rotating mechanism 71 has four evenly distributed grooves on its outer side for matching and positioning with the spring pin assembly 73, ensuring that the jig plate 11 can accurately return to its original position after rotation. The spring pin assembly 73 is mounted on the main structure 69 and adopts an elastic telescopic structure for engaging with the grooves of the rotating mechanism 71. The rotating mechanism 71 can only stop rotating when the spring pin is inserted into the groove, achieving precise positioning of the jig plate 11 and preventing displacement after resetting.

[0071] The photoelectric switch assembly 66 is installed at the corresponding position on the main structure 69. It has a precise sensing function and is used to sense the limit point of the fixture plate 11 to detect whether the fixture plate 11 has completed its reset. When the fixture plate 11 is detected to have been precisely reset, a signal is sent to the lifting cylinder 68 to control the lifting cylinder 68 to retract, allowing the fixture plate 11 to smoothly fall back onto the double-speed chain conveyor line. The rotation limit assembly 67 is installed on the main structure 69 to limit the rotation angle of the rotation mechanism 71, preventing damage to the fixture plate 11 and the product due to excessive rotation angle.
