Description

Technical Field

[0001] This invention belongs to the technical field of power testing devices, specifically relating to a comprehensive power automation testing device. Background Technology

[0002] Power equipment refers to the general term for electrical equipment, facilities and their auxiliary systems used in the entire process of power generation, transmission, transformation, distribution and consumption. It is the core component of the power system to realize energy conversion, transmission, control and protection. It includes power generation equipment, transformation equipment, transmission equipment, distribution equipment and protection and control equipment. However, small transformers are one of the power equipment. Therefore, the automated integrated testing device is an intelligent device that integrates electrical performance testing, safety testing, mechanical characteristic verification and data analysis functions. It is used to conduct fully automatic, high-precision and high-efficiency factory inspection or type testing on small transformers (such as transformers for electronic equipment, power adapter transformers, control transformers, etc.).

[0003] Currently, when testing electrical equipment, such as small transformers, the equipment is typically inserted directly into a test probe bed. The test probes on the transformer are aligned with the terminals on the test probe bed, and a comprehensive test is performed on the transformer using a testing machine, including electrical performance and safety performance tests. Because the test probes on transformers are relatively thin and long, the current testing process is usually done manually, making it impossible to visually detect whether the test probes have slight bends. If they are not straightened before insertion, the test probes may not be able to fully match the terminals on the test probe bed, resulting in inaccurate test results and affecting the quality of the final product. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a power automation integrated testing device.

[0005] The technical solution adopted to solve the above technical problems is: a power automation integrated testing device, including a support frame, a first conveying component is fixedly installed on one side of the top of the support frame, and a movable lifting mechanism is fixedly installed at the rear end of the top center of the support frame. The mobile lifting mechanism is equipped with a material transfer mechanism, and the top of the support frame is equipped with a straightening mechanism at the front end of the mobile lifting mechanism. The material transfer mechanism is equipped with a rotating mechanism. A comprehensive testing mechanism is fixedly installed on the top of the support frame near the material transfer mechanism. A second conveying assembly is fixedly installed on the other side of the top of the support frame. The first conveying assembly is used for loading the transformer, and the second conveying assembly is used for unloading the transformer.

[0006] Furthermore, a stop is fixedly connected to one side of the top of the first conveying assembly.

[0007] Using the above technical solution, when testing a transformer, the staff places the transformer onto the first conveying component. The first conveying component automatically transports the transformer, and when the first transformer is pressed against the stop block, the moving lifting mechanism starts to operate, thus realizing the transportation of the transformer.

[0008] Furthermore, the movable lifting mechanism includes a support plate fixedly connected to the rear end of the top center of the support frame. Two first slide rails are fixedly connected to the front end of the support plate, and a rack is fixedly connected to the top of the support plate. A movable plate is slidably connected to the front end of the two first slide rails. A first motor is fixedly installed on one side of the rear top of the movable plate. A first gear is fixedly connected to the outer wall of the output shaft of the first motor. A first cylinder is fixedly installed at the top center of the front end of the movable plate. Two second slide rails are fixedly connected to the bottom front end of the movable plate. The first gear meshes with the rack.

[0009] With the above technical solution, when a transformer needs to be transferred, the first motor is started, and the output shaft rotates to drive the first gear, which meshes and rolls on the rack, thereby driving the movable plate to move and realize the horizontal movement of the transfer mechanism. At the same time, the first cylinder is started, and the piston extends and retracts to push the transfer mechanism, realizing the vertical movement of the transfer mechanism, thus facilitating the loading and unloading of transformers and improving testing efficiency.

[0010] Furthermore, the material transfer mechanism includes a connecting plate fixedly connected to the bottom end of the piston of the first cylinder, and a first parallel gripper, a second parallel gripper, and a third parallel gripper are fixedly installed at the front end of the connecting plate.

[0011] With the above technical solution, when the first transformer is close to the stop block, the first parallel gripper, under the action of the moving lifting mechanism, drives the first transformer to the straightening mechanism, so as to facilitate the straightening of the test probe. The second parallel gripper then transports the straightened transformer to the rotating mechanism, and the third parallel gripper rotates the tested transformer to the second conveying component. Multiple cylinders operate synchronously to realize the automated transfer of the transformer. Multiple processes are carried out simultaneously, improving testing efficiency.

[0012] Furthermore, the straightening mechanism includes a turntable rotatably connected to a support frame, a rotating shaft fixedly connected to the center of the turntable, a second gear fixedly connected to the bottom of the outer wall of the rotating shaft, a mounting frame fixedly connected to the bottom of the support frame near the turntable, a second motor fixedly mounted at the bottom of the mounting frame, a third gear fixedly connected to the outer wall of the output shaft of the second motor, two first placement seats fixedly connected to the top of the turntable, a fixing frame fixedly connected to the top of the support frame near the turntable, a second cylinder fixedly mounted at the rear end of the fixing frame, and a straightening seat fixedly connected to the bottom end of the piston of the second cylinder.

[0013] With the above technical solution, when the transformer is rotated into the first placement seat near the first parallel gripper, the second motor is started. The output shaft rotates, driving the third gear to rotate, which in turn drives the second gear to rotate. This causes the first placement seat containing the transformer to rotate 180 degrees, so that the transformer is positioned directly below the straightening seat. Another first placement seat is rotated to be near the first parallel gripper, facilitating the placement of the next transformer. At this time, the second cylinder is started, and the piston pushes the straightening seat, which in turn pushes multiple limit rods, causing the limit rods to insert into their corresponding limit holes. Simultaneously, the slightly bent test needle on the transformer first contacts the corresponding guide arc groove, providing a guiding effect, allowing the test needle to slowly insert into the straightening hole. When the straightening seat is fully in contact with the first placement seat, the test needle is straightened. After straightening, the straightening seat is reset by the second cylinder, and the turntable rotates 180 degrees again, causing the straightened transformer to rotate 180 degrees, facilitating subsequent material transfer.

[0014] Furthermore, the third gear meshes with the second gear.

[0015] Through the above technical solution, the rotation of the third gear drives the rotation of the second gear, which in turn drives the first mounting base containing the transformer to rotate, achieving rapid switching and facilitating subsequent straightening of the transformer.

[0016] Furthermore, limit holes are provided at the top four corners of both first placement seats, and limit rods are fixedly connected to the bottom four corners of the straightening seat. Multiple straightening holes are provided at the bottom of the straightening seat, and guide arc grooves are provided at the bottom of the straightening seat near the straightening holes.

[0017] The above technical solution straightens the test pins on the transformer before testing to facilitate subsequent testing by testing equipment, thereby improving the accuracy of test data and improving product quality.

[0018] Furthermore, the rotating mechanism includes a finger cylinder fixedly connected to the front end of the connecting plate. The finger cylinder is provided with two claw plates, and a connecting shaft is rotatably connected to each of the two claw plates. A third motor is fixedly installed on one of the claw plates. One end of the output shaft of the third motor is fixedly connected to the adjacent connecting shaft. A claw head is fixedly connected to one end of each of the two connecting shafts. A slot and a strip are respectively opened on the two claw heads. A second placement seat is fixedly connected to the top of the support frame near the lower part of the two claw heads.

[0019] With the above technical solution, after the transformer is straightened, it is rotated to the second placement seat by the second parallel pneumatic gripper. At this time, the test needles on the transformer are facing upwards. Then, the finger cylinder is moved above the transformer by the moving lifting mechanism. The finger cylinder is activated, pushing the two claw plates, thereby pushing the two claw heads to clamp the transformer. At the same time, the locking strip on one claw head is inserted into the locking groove on the other claw head, so that the two claw heads are joined together. Then, the third motor is activated, and the output shaft of the third motor drives the connected shaft to rotate. Since the transformer is clamped, it is driven to rotate 180 degrees, so that the test needles of the transformer face downwards, making it easier to insert them into the integrated testing mechanism and improve testing efficiency.

[0020] Furthermore, the integrated testing mechanism includes a test base fixedly connected to the top of the support frame. A needle bed is mounted on the top of the test base, and multiple terminals are provided on the needle bed. Sliding grooves are provided on both inner walls of the test base. A mounting base is fixedly connected to the top of the support frame near the test base. A third cylinder is fixedly mounted on the top of the mounting base. A guide plate is fixedly connected to one end of the piston of the third cylinder. Multiple through holes are provided on the top of the guide plate. Springs are fixedly connected to both the front and rear ends of the guide plate. A testing instrument is fixedly mounted on the other front end of the top of the support frame. A wire is fixedly connected between the testing instrument and the needle bed.

[0021] Using the above technical solution, after rotating the transformer, it is quickly placed on the guide plate directly through the moving lifting mechanism and finger cylinder, so that the test pins on the transformer pass through the corresponding sockets. The finger cylinder resets, the third cylinder is activated, and the piston pushes the guide plate, thereby pushing the transformer. The guide plate slides on the needle bed, and multiple sockets are aligned with the corresponding terminals, so that the bottom ends of multiple test pins on the transformer contact the corresponding terminals. Multiple terminals are connected to the corresponding test pins, and the test information is transmitted to the tester through wires for testing. This enables rapid testing of the transformer, and the test results are observed on the tester. The operation is simple and highly automated.

[0022] Furthermore, the two sides of the guide plate are slidably connected to the corresponding slide grooves, and one end of each of the multiple springs is fixedly connected to the corresponding slide groove.

[0023] With the above technical solution, when the guide plate is pushed, it compresses the corresponding spring. Multiple springs provide a certain buffer, and the guide plate moves back and forth, allowing for rapid testing of each transformer and improving testing efficiency.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention designs a straightening mechanism to straighten the test needles on the transformer before testing, so as to facilitate subsequent testing by the testing equipment, thereby improving the accuracy of the test data and thus improving the quality of the product; (2) The present invention designs a moving lifting mechanism and a rotating mechanism to quickly rotate the straightened transformer 180 degrees, so that the test needles on the transformer face down, so as to facilitate subsequent insertion into the test needle bed and improve testing efficiency; (3) The present invention designs a comprehensive testing mechanism to quickly test the data inside the transformer through the test needle bed and to quickly test each transformer, thereby improving the overall testing efficiency and realizing automated testing.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-4As shown, a power automation integrated testing device of this embodiment includes a support frame 1. A first conveying component 2 is fixedly installed on one side of the top of the support frame 1. A stop block 21 is fixedly connected to one side of the top of the first conveying component 2. When testing a transformer, the operator puts the transformer onto the first conveying component 2. The transformer is automatically transported by the first conveying component 2. When the first transformer is close to the stop block 21, the moving lifting mechanism 3 starts to operate to realize the transport of the transformer. A movable lifting mechanism 3 is fixedly installed at the rear end of the top center of the support frame 1. The movable lifting mechanism 3 includes a support plate 301 fixedly connected to the rear end of the top center of the support frame 1. Two first slide rails 302 are fixedly connected to the front end of the support plate 301. A rack 303 is fixedly connected to the top of the support plate 301. A movable plate 304 is slidably connected to the front end of the two first slide rails 302. A first motor 305 is fixedly installed on one side of the rear top of the movable plate 304. A first gear 306 is fixedly connected to the outer wall of the output shaft of the first motor 305. A first cylinder 307 is fixedly installed at the top center of the front end of the movable plate 304. Two second cylinders 306 are fixedly connected to the bottom front end of the movable plate 304. The slide rail 308 has a first gear 306 meshing with a rack 303. When the transformer needs to be transferred, the first motor 305 is started, and the output shaft rotates to drive the first gear 306, causing the first gear 306 to mesh and roll on the rack 303, thereby driving the movable plate 304 to move, realizing the horizontal movement of the transfer mechanism 4. At the same time, the first cylinder 307 is started, and the piston extends and retracts to push the transfer mechanism 4, realizing the vertical movement of the transfer mechanism 4, thereby facilitating the loading and unloading of the transformer and improving testing efficiency. The second conveying component 8 is fixedly installed on the other side of the top of the support frame 1. The first conveying component 2 is used for loading the transformer, and the second conveying component 8 is used for unloading the transformer.

[0029] like Figures 1-4 As shown, a transfer mechanism 4 is installed on the mobile lifting mechanism 3. The transfer mechanism 4 includes a connecting plate 401 fixedly connected to the bottom end of the piston of the first cylinder 307. A first parallel gripper 402, a second parallel gripper 403, and a third parallel gripper 404 are fixedly installed at the front end of the connecting plate 401. When the first transformer is close to the stop block 21, the first parallel gripper 402, under the action of the mobile lifting mechanism 3, drives the first transformer to the straightening mechanism 5, thereby facilitating the straightening of its test needle. The second parallel gripper 403 transports the straightened transformer to the rotating mechanism 6, and the third parallel gripper 404 transfers the tested transformer to the second conveying component 8. Multiple cylinders operate synchronously to realize the automated transfer of transformers. Multiple processes are carried out simultaneously, improving testing efficiency.

[0030] like Figures 1-8As shown, a straightening mechanism 5 is installed at the top of the support frame 1, located at the front end of the movable lifting mechanism 3. The straightening mechanism 5 includes a turntable 501 rotatably connected to the support frame 1. A rotating shaft 502 is fixedly connected to the center of the turntable 501. A second gear 503 is fixedly connected to the bottom of the outer wall of the rotating shaft 502. A mounting frame 504 is fixedly connected to the bottom of the support frame 1 near the turntable 501. A second motor 505 is fixedly installed at the bottom of the mounting frame 504. A third gear 506 is fixedly connected to the outer wall of the output shaft of the second motor 505. Two first placement seats 507 are fixedly connected to the top of the turntable 501. A fixing frame 508 is fixedly connected to the top of the support frame 1 near the turntable 501. A second cylinder 509 is fixedly installed at the rear end of the frame 508. A straightening seat 510 is fixedly connected to the bottom end of the piston of the second cylinder 509. When the transformer is rotated into the first placement seat 507 near the first parallel gripper 402, the second motor 505 is started. The output shaft rotates, driving the third gear 506 to rotate, which in turn drives the second gear 503 to rotate. This causes the first placement seat 507 containing the transformer to rotate 180 degrees, positioning the transformer directly below the straightening seat 510. The other first placement seat 507 is then rotated to a position near the first parallel gripper 402, facilitating the placement of the next transformer. At this point, the second cylinder 509 is started again, pushing the piston... The moving straightening seat 510 pushes multiple limiting rods 5101, causing them to insert into their corresponding limiting holes 5071. Simultaneously, the slightly bent test needle on the transformer first contacts the corresponding guide groove 5103, providing a guiding effect and allowing the test needle to slowly insert into the straightening hole 5102. When the straightening seat 510 is fully in contact with the first placement seat 507, the test needle is straightened. After straightening, the straightening seat 510 is reset by the second cylinder 509, and the turntable 501 rotates 180 degrees, causing the straightened transformer to rotate 180 degrees for subsequent material transfer. The third gear 506 meshes with the second gear 503. The rotation of the first gear 507 causes the second gear 503 to rotate, which in turn causes the first placement seat 507 containing the transformer to rotate, enabling rapid switching and facilitating subsequent straightening of the transformer. Limiting holes 5071 are provided at the four corners of the top of both first placement seats 507, and limiting rods 5101 are fixedly connected to the four corners of the bottom of the straightening seat 510. Multiple straightening holes 5102 are provided at the bottom of the straightening seat 510, and guide grooves 5103 are provided at positions near the straightening holes 5102 on the bottom of the straightening seat 510. Before testing, the test pins on the transformer are straightened to facilitate subsequent testing by the testing equipment, thereby improving the accuracy of the test data and ultimately improving product quality.

[0031] like Figures 1-9As shown, a rotating mechanism 6 is installed on the material transfer mechanism 4. The rotating mechanism 6 includes a finger cylinder 602 fixedly connected to the front end of the connecting plate 401. The finger cylinder 602 is provided with two claw plates 603. Each claw plate 603 is rotatably connected to a connecting shaft 604. A third motor 608 is fixedly installed on one of the claw plates 603. One end of the output shaft of the third motor 608 is fixedly connected to the adjacent connecting shaft 604. Each end of the two connecting shafts 604 is fixedly connected to a claw head 605. The two claw heads 605 are respectively provided with a slot 606 and a clip 607. A second placement seat 601 is fixedly connected to the top of the support frame 1 near the lower part of the two claw heads 605. After the transformer is straightened, it is rotated to the first position by the second parallel claw 403. The transformer is placed on the base 601 with the test probes facing upwards. The lifting mechanism 3 moves the finger cylinder 602 above the transformer, activates the finger cylinder 602, pushes the two claw plates 603, and thus pushes the two claw heads 605 to clamp the transformer. At the same time, the locking strip 607 on one claw head 605 is inserted into the locking slot 606 on the other claw head 605, so that the two claw heads 605 are joined together. Then, the third motor 608 is activated, and the output shaft of the third motor 608 rotates, driving the connected shaft 604 to rotate. Since the transformer is clamped, it rotates 180 degrees, so that the test probes of the transformer face downwards, making it easier to insert them into the integrated testing mechanism 7 later, thereby improving testing efficiency.

[0032] like Figures 1-10As shown, a comprehensive testing mechanism 7 is fixedly installed on the top of the support frame 1 near the lower part of the transfer mechanism 4. The comprehensive testing mechanism 7 includes a test seat 701 fixedly connected to the top of the support frame 1. A needle bed 702 is installed on the top of the test seat 701, and multiple terminals 703 are provided on the needle bed 702. Sliding grooves 704 are provided on the inner walls of both sides of the test seat 701. A mounting base 705 is fixedly connected to the top of the support frame 1 near the test seat 701. A third cylinder 706 is fixedly installed on the top of the mounting base 705. One end of the piston of the third cylinder 706 is fixedly connected to a guide plate 707. Multiple through holes 708 are provided on the top of the guide plate 707. Springs 709 are fixedly connected to both the front and rear ends of the guide plate 707. A testing instrument 710 is fixedly installed on the other front end of the top of the support frame 1. A wire 711 is fixedly connected between the testing instrument 710 and the needle bed 702. After rotating the transformer, it is quickly placed on the guide plate 707 directly via the moving lifting mechanism 3 and the finger cylinder 602, allowing the transformer to... The test pins on the transformer pass through the corresponding sockets 708. The finger cylinder 602 resets, activating the third cylinder 706. The piston pushes the guide plate 707, thereby pushing the transformer. The guide plate 707 slides on the needle bed 702, and the multiple sockets 708 align with the corresponding terminals 703. This allows the bottom ends of the multiple test pins on the transformer to contact the corresponding terminals 703. The multiple terminals 703 connect with the corresponding test pins, transmitting the test information to the tester 710 via the wire 711 for testing. This enables rapid testing of the transformer, and the test results are observed on the tester 710. The operation is simple and highly automated. The two sides of the guide plate 707 are slidably connected to the corresponding slide grooves 704. One end of each of the multiple springs 709 is fixedly connected to the corresponding slide groove 704. When the guide plate 707 is pushed, it compresses the corresponding springs 709, providing a certain buffer through the multiple springs 709. The guide plate 707 moves back and forth, allowing for rapid testing of each transformer and improving testing efficiency.

[0033] The working principle of this embodiment is as follows: the operator puts the transformer onto the first conveying component 2, and the first conveying component 2 automatically transports it so that the first transformer is close to the stop block 21. The first motor 305 is started, and the output shaft rotates to drive the first gear 306, so that the first gear 306 meshes and rolls on the rack 303, thereby driving the movable plate 304 to move, realizing the horizontal movement of the material transfer mechanism 4. At the same time, the first cylinder 307 is started, and the piston extends and retracts to push the material transfer mechanism 4, realizing the vertical movement of the material transfer mechanism 4. When the first parallel gripper 402 is moved close to the first transformer, the first parallel gripper 402 clamps the transformer, and the moving lifting mechanism 3 transports it into the first placement seat 507. At this point, the second motor 505 is activated, which drives the third gear 506 to rotate via its output shaft. This, in turn, drives the second gear 503 to rotate, causing the first placement seat 507 containing the transformer to rotate 180 degrees. The transformer is then positioned directly below the straightening seat 510, and the other first placement seat 507 is rotated to a position closer to the first parallel pneumatic gripper 402, facilitating the placement of the next transformer. Then, the second cylinder 509 is activated, pushing the straightening seat 510 via its piston, which in turn pushes multiple limit rods 51. 01, so that multiple limiting rods 5101 are inserted into the corresponding limiting holes 5071 respectively. At the same time, the slightly bent test needle on the transformer first contacts the corresponding guide arc groove 5103, which plays a guiding role, so that the test needle is slowly inserted into the straightening hole 5102. When the straightening seat 510 is completely in contact with the first placement seat 507, the test needle is straightened. After the straightening is completed, the straightening seat 510 is reset by the second cylinder 509, and the turntable 501 rotates 180 degrees, driving the straightened transformer to rotate 180 degrees. The straightened transformer is then transferred to the second placement seat 601 via the second parallel gripper 403. At this time, the test needles on the transformer are facing upwards. The finger cylinder 602 is then moved above the transformer via the moving lifting mechanism 3. The finger cylinder 602 is activated, pushing the two claw plates 603, which in turn pushes the two claw heads 605 to clamp the transformer. At the same time, the locking strip 607 on one claw head 605 is inserted into the locking groove 606 on the other claw head 605, so that the two claw heads 605 are joined together. The third motor 608 is then activated, and the output shaft of the third motor 608 rotates, driving the connected shaft 604 to rotate. Since the transformer is clamped, it rotates 180 degrees, so that the test needles of the transformer are facing downwards. When the rotated transformer is moved to the top of the guide plate 707 by the moving lifting mechanism 3, it is precisely inserted into the multiple sockets 708 on the guide plate 707. The finger cylinder 602 is reset, and the third cylinder 706 is activated. The piston pushes the guide plate 707, thereby pushing the transformer, so that the guide plate 707 slides on the needle bed 702, and the multiple sockets 708 are aligned with the corresponding terminals 703. This makes the bottom of the multiple test pins on the transformer contact the corresponding terminals 703, and the multiple terminals 703 are connected to the corresponding test pins. The test information is transmitted to the tester 710 through the wire 711 and tested. The test results are observed through the tester 710. After the test is completed, the tested transformer is transported to the second conveying assembly 8 by the third parallel gripper 404 and the moving lifting mechanism 3, realizing automated operation.
