Description

Technical Field

[0001] This utility model relates to the field of circuit board testing technology, and in particular to a testing device for the main control circuit board of a high-voltage insulation testing equipment. Background Technology

[0002] A circuit board is an important electronic component. It consists of a substrate made of insulating materials (such as fiberglass), conductive copper foil circuitry, and various electronic components (such as chips, resistors, capacitors, and inductors). Physically, the copper foil circuitry is printed onto the substrate using processes such as etching, forming specific circuit connections. These circuit connections link the various electronic components according to design requirements, enabling signal transmission, current flow, and energy conversion between them. Therefore, testing the main control circuit board of high-voltage insulation testing equipment is crucial. First, it ensures the integrity of its functionality. The main control circuit board undertakes core tasks such as control logic and signal processing in the entire high-voltage insulation testing equipment. Testing verifies whether it can accurately process input signals and output correct control signals, such as correctly identifying the insulation resistance value and issuing corresponding alarms or normal operation commands. Second, testing ensures safety. Because high-voltage insulation testing equipment involves a high-voltage environment, a faulty main control circuit board may lead to misjudgments in high-voltage insulation testing, potentially causing electrical safety accidents such as electric shock and equipment damage in practical applications. Third, testing helps improve product reliability.

[0003] However, in the existing testing devices for the main control circuit boards of some high-voltage insulation testing equipment, after the main control circuit board is tested, operators usually need to use specific clamps to remove the circuit board for subsequent testing. Removing the circuit board using clamps requires extreme care to ensure no damage is caused to sensitive components on the circuit board. This requires operators to have certain professional skills and experience, thus increasing labor costs. Furthermore, since this process needs to be repeated after each test, overall work efficiency is significantly affected. Secondly, frequent use of clamps to remove and place circuit boards can lead to wear or damage to the clamps themselves, affecting the accuracy and reliability of subsequent tests. This not only increases equipment maintenance costs but also causes deviations in test results due to clamp problems, negatively impacting the quality control of the entire testing process. Therefore, to address these shortcomings, a testing device for the main control circuit boards of high-voltage insulation testing equipment is proposed to solve these problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a testing device for the main control circuit board of a high-voltage insulation testing equipment, aiming to improve the problem that some existing testing devices for the main control circuit board of high-voltage insulation testing equipment cannot achieve rapid material cutting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A testing device for the main control circuit board of a high-voltage insulation testing equipment includes an outer frame. A drive assembly for providing power is provided on the top of the outer frame. Two support platforms are fixedly connected inside the outer frame. Two inclined blocks are fixedly connected to the rear side of the inner side of the outer frame. A connecting frame is slidably connected inside each of the two inclined blocks. A limit block is fixedly connected to the top of each of the two connecting frames. A pressing plate is slidably connected to the top of each of the two inclined blocks. Two telescopic rods are fixedly connected to the top of each of the two pressing plates. A limit plate is fixedly connected to the top of each of the multiple telescopic rods. Two sliding rods are slidably connected inside each of the two inclined blocks. Two sliding grooves are formed inside each of the two inclined blocks. Springs are sleeved on the outside of each of the multiple sliding rods. Two push plates are fixedly connected to the front side of each of the multiple sliding rods. A guide groove is formed inside each of the two inclined blocks.

[0007] As a further description of the above technical solution:

[0008] The drive assembly includes a cylinder, the bottom of which is mounted on the top of the outer frame, a push rod is fixedly connected to the output end of the cylinder, and a pressure plate is fixedly connected to the outside of the push rod.

[0009] As a further description of the above technical solution:

[0010] The bottom of the pressure plate has two sliding grooves and two limiting grooves. The bottom of the push rod is fixedly connected to a connecting plate. Rotating plates are rotatably connected to both the left and right sides of the connecting plate. Clamping plates are rotatably connected to the opposite sides of the rotating plates. Positioning abutments are fixedly connected to the opposite sides of the interior of the two bearing platforms.

[0011] As a further description of the above technical solution:

[0012] Multiple connecting rods are fixedly connected to the bottom of the pressure plate, and two detection plates are fixedly connected to the bottom of the multiple connecting rods. An operating table is fixedly connected to the inner middle side of the outer frame. A display screen is provided on the front side of the operating table. A main control box is installed on the inner rear side of the outer frame. A base is fixedly connected to the bottom of the outer frame.

[0013] As a further description of the above technical solution:

[0014] The pressure plate is externally slidably connected to the inside of the outer frame, and the clamping plate is externally slidably connected to the inside of the support platform;

[0015] As a further description of the above technical solution:

[0016] The connecting frame is externally slidably connected to the inside of the guide groove, and the sliding rod is externally slidably connected to the inside of the sliding groove;

[0017] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, after the test is completed, the cylinder drives the push rod and the pressure plate to move upward, causing the clamping plate to release the circuit board. At this time, the spring rebounds and pushes the push plate to move backward, pushing the tested circuit board out of the carrier platform, realizing automatic unloading of the circuit board, thereby greatly improving the testing efficiency, reducing the time and labor intensity of manual operation, and also reducing the risk of circuit board damage caused by human factors.

[0023] 2. This invention allows for the simultaneous testing of two circuit boards, improving testing efficiency. The design of the rotating plate and clamping plate ensures stable clamping of the circuit boards. When the connecting plate moves downwards, the rotating plate rotates, causing the clamping plate to move inwards and secure the main control circuit board. This ensures the stability of the circuit boards during testing, avoiding inaccurate test results or circuit board damage caused by movement or shaking. Furthermore, the dual-station testing function enables the equipment to handle a large number of circuit board testing tasks more efficiently, further improving work efficiency.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3This utility model provides an embodiment of a testing device for the main control circuit board of a high-voltage insulation testing equipment. The device includes an outer frame 1, which serves as the main framework for the entire device and provides a foundation for the installation and support of various components. A drive assembly for providing power is located at the top of the outer frame 1. This drive assembly includes a cylinder 2, the bottom of which is mounted on the top of the outer frame 1. The cylinder 2 is the power source for the testing device, providing driving force for the entire testing process. A push rod 3 is fixedly connected to the output end of the cylinder 2. A pressure plate 4 is fixedly connected to the outside of the push rod 3, and the pressure plate 4 is slidably connected to the inside of the outer frame 1. The push rod 3 transmits the output force of the cylinder 2 to the pressure plate 4, enabling the pressure plate 4 to move up and down. Two support platforms 5 are fixedly connected inside the outer frame 1. These support platforms 5 are structures used to place the main control circuit board within the testing device. Two inclined blocks 6 are fixedly connected to the rear side of the inner side of the outer frame 1. A connecting frame 7 is slidably connected inside each of the inclined blocks 6. During the test, when the pressing plate 9 is compressed, the connecting frame 7 slides rearward inside the inclined block 6. Limiting blocks 8 are fixedly connected to the top of both connecting frames 7. The limiting blocks 8 are structures used in the testing device to limit the range of motion of the connecting frames 7. Squeezing plates 9 are slidably connected to the top of both inclined blocks 6. The rear side of the squeezing plates 9 is in contact with the outside of the connecting frames 7. When the pressure plate 4 moves downward, the squeezing plates 9 are squeezed and move backward, pushing the connecting frames 7 to slide inside the inclined blocks 6.

[0034] Reference Figures 2 to 4Two telescopic rods 10 are fixedly connected to the top of each of the two extrusion plates 9. During the test, when the extrusion plate 9 is compressed, the telescopic rods 10 will extend and retract with the movement of the extrusion plate 9, ensuring the stability of the extrusion plate 9 during movement. Limiting plates 11 are fixedly connected to the top of each of the multiple telescopic rods 10. Two sliding rods 12 are slidably connected inside each of the two inclined blocks 6. Two sliding grooves 13 are formed inside each of the two inclined blocks 6. The outside of the sliding rods 12 is slidably connected inside the sliding grooves 13. The sliding grooves 13 can limit the movement direction of the sliding rods 12, ensuring the stability of the push plate 15 during movement. Springs 14 are sleeved on the outside of each of the multiple sliding rods 12. One end of the spring 14 is fixedly connected inside the inclined block 6, and the other end of the spring 14 is fixedly connected to the outside of the push plate 15. When the extrusion plate 9 is compressed, the connecting frame 7 will slide backward inside the inclined block 6, pushing the push plate 15 forward. At this time, the sliding rods 12 will slide inside the inclined block 6, and the springs 14 will be compressed. Two push plates 15 are fixedly connected to the front of multiple sliding rods 12. The bottom of the push plates 15 is slidably connected to the inside of the support platform 5. When the pressure is removed, the spring 14 will rebound, pushing the push plates 15 to move backward, thereby realizing automatic unloading of the main control circuit board. Guide grooves 18 are opened inside the two tilting blocks 6. The outside of the connecting frame 7 is slidably connected to the inside of the guide grooves 18. The guide grooves 18 can limit the movement direction of the connecting frame 7 and ensure the stability of the push plates 15 during movement.

[0035] Reference Figures 3 to 5 The bottom of the pressure plate 4 has two sliding grooves 16 and two limiting grooves 17. A connecting plate 21 is fixedly connected to the bottom of the push rod 3. Rotating plates 22 are rotatably connected to both sides of the connecting plate 21. Clamping plates 23 are rotatably connected to opposite sides of the rotating plates 22. The clamping plates 23 are slidably connected to the outside of the support platform 5. During testing, when the connecting plate 21 moves downwards, the rotating plates 22 rotate, causing the clamping plates 23 to move inwards and clamp the main control circuit board. When the connecting plate 21 moves upwards, the rotating plates 22 rotate in the opposite direction, causing the clamping plates 23 to move outwards and release the main control circuit board. Positioning abutments 26 are fixedly connected to opposite sides of the interior of the two support platforms 5.

[0036] Reference Figure 1 and Figure 6Multiple connecting rods 19 are fixedly connected to the bottom of the pressure plate 4. Two detection plates 20 are fixedly connected to the bottom of each connecting rod 19. During testing, the connecting rods 19 move up and down with the pressure plate 4, causing the detection plates 20 to contact the main control circuit board, thus enabling the detection of the main control circuit board. Various detection sensors and circuits are typically installed on the detection plates 20, which can detect the electrical and insulation performance of the main control circuit board. An operating table 24 is fixedly connected to the inner middle of the outer frame 1. The operating table 24 is the structure in the testing device used to control the entire testing process. Various control buttons and switches are typically installed on the operating table 24, allowing operators to control components such as the cylinder 2 and the detection plates 20. A display screen 25 is located on the front of the operating table 24, which is used to display various parameters and data during the testing process. A main control box 27 is installed on the inner rear of the outer frame 1, and a base 28 is fixedly connected to the bottom of the outer frame 1. The base 28 is the bottom support structure of the testing device, providing stable support for the entire device.

[0037] Working principle: When using the testing device with this main control circuit board, the main control circuit board can first be placed inside the support platform 5. At this time, the cylinder 2 can be controlled by the operating table 24 to drive the push rod 3 and the pressure plate 4 to move, thereby causing the pressure plate 4 and the connecting plate 21 to move downward, which in turn causes the rotating plate 22 to rotate. Then, the clamping plate 23 can slide inside the support platform 5. At this time, the circuit board can be clamped and fixed by the clamping plate 23, thereby realizing the dual-station testing of the circuit board. As the pressure plate 4 moves downward, it will drive the telescopic rod 10 to move, which will cause the telescopic rod 10 to extend and retract. At this time, the pressing plate 9 will press the limiting block 8 and the connecting frame 7, causing the connecting frame 7 to slide into the tilting block 6, which in turn allows the sliding rod 12 to slide inside the sliding groove 13 and compresses the spring 14. This causes the push plate 15 to move backward. Then, when the detection plate 20 contacts the circuit board, the circuit board can be detected. After the detection is completed, the cylinder 2 can be activated to lift the connecting plate 21 upward, which will reset the clamping plate 23. As the pressure plate 4 moves upward, the spring 14 will rebound, which will reset the push plate 15. The detected circuit board can then be pushed out with the help of the push plate 15, thus completing the automatic unloading of the circuit board.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
