Technical Field
[0001] This invention relates to the technical field of circuit board repair and testing, and in particular to a circuit board testing device and method based on the repair of mass-powered power generation equipment. Background Technology
[0002] Mass-energy power generation equipment refers to devices that utilize substances (such as biomass, nuclear fuel, etc.) to release energy and convert it into electrical energy through physical or chemical processes. Currently, common mass-energy power generation equipment mainly includes biomass power generation equipment, waste incineration power generation equipment, and nuclear power generation equipment. Because mass-energy power generation equipment is used in harsh environments, its internal circuit boards may be damaged due to environmental factors, electrical problems, mechanical and operational factors. When manufacturers handle after-sales service for faulty circuit boards, since staff cannot detect the cause of the fault in a short time, they usually replace the circuit board with a new one and take the faulty circuit board back to the manufacturer for unified repair and reuse.
[0003] Currently, ICT testing machines are commonly used to detect whether circuit board faults are caused by component pin problems. While effective in testing circuit boards, they still have the following drawbacks: Existing ICT testing machines typically require manual intervention to hold the circuit board in a designated location using clamping components and to connect probes from a probe board to the circuit board for component pin testing. Because board holding requires manual operation, existing ICT testing machines cannot achieve continuous automatic testing. However, manufacturers often test a large number of circuit boards simultaneously, making manual testing inefficient. Therefore, a circuit testing device is designed to achieve continuous automatic testing of multiple circuit boards without manual intervention. Furthermore, this device can classify and collect circuit boards with component pin problems and those with normal component pins, effectively improving the efficiency of circuit board repair and testing. Summary of the Invention
[0004] In view of the problem that existing ICT testing machines cannot continuously perform fault detection on multiple circuit boards to be repaired, a circuit board testing device and method based on the maintenance of energy-powered equipment is proposed.
[0005] This application provides a circuit board testing device and method based on the maintenance of mass-energy power generation equipment. The purpose is to: by setting up an automatic detection and fixing unit, when the feeding conveyor transports the circuit board to the fixing table through the docking plate, during the detection probe plate moving downward for detection, the docking plate and the circuit board are driven to move towards the electric door by the trigger component. At the same time, the setting of the concave trigger plate allows the docking plate to quickly reset once when it brings the circuit board towards the electric door. During the reset process, the circuit board is completely placed above the electric door by inertia. When the concave trigger plate drives the docking plate to move horizontally again, the horizontally moving docking plate is used to fix and position the four sides of the circuit board, ensuring that the circuit board is in the designated position and fixed when the detection probe plate presses down and contacts the circuit board.
[0006] The technical solution of the present invention is: a circuit board testing device based on the maintenance of mass-energy power generation equipment, used to test the circuit board to be repaired, including a fixed platform, two support plates are provided on the upper end of the fixed platform, a testing platform is provided on the upper end of the two support plates, and an automatic testing and fixing unit is installed between the fixed platform and the testing platform.
[0007] The automatic detection and fixing unit includes multiple limiting grooves on both sides of the fixing platform, sliding rods slidably disposed in the multiple limiting grooves, docking plates disposed between the multiple sliding rods, a detection mechanism disposed at the lower end of the detection platform, an electric door disposed at the bottom end of the fixing platform, two bearing plates disposed on one side of the fixing platform, and a feeding conveyor and a discharging conveyor disposed between the two bearing plates. A triggering component is installed between the docking plate and the detection mechanism.
[0008] The docking plate includes a first point and a second point. When the docking plate is located at the first point, it is used to connect the feeding conveyor and the fixed platform. When the docking plate moves from the first point to the second point, it is used to position the circuit board. When the docking plate is located at the second point, it is used to fix the circuit board.
[0009] Furthermore, the testing mechanism includes multiple telescopic rods disposed at the lower end of the testing platform, a testing probe plate disposed at the lower end of the multiple telescopic rods, an electric rod disposed inside the testing platform, the telescopic end of the electric rod being fixedly connected to the telescopic rod, the testing probe plate being located directly above the electric door, multiple long rods disposed at the lower end of the testing probe plate, multiple test plates disposed at the lower end of the multiple long rods, and multiple test probes disposed at the lower end of the test plates.
[0010] Furthermore, the triggering assembly includes an extension plate disposed on the side wall of the detection probe plate, a concave trigger plate disposed at the lower end of the extension plate, square grooves formed on the side walls of the two support plates, two mounting shafts disposed on the inner walls of the two square grooves, and V-shaped mating plates disposed on the two mounting shafts. A transmission element is installed between the V-shaped mating plate and the corresponding sliding rod.
[0011] Furthermore, the transmission element includes a trigger rod slidably disposed inside the two support plates, one end of the trigger rod being hinged to a V-shaped mating plate, a connecting plate disposed at the end of the trigger rod away from the V-shaped mating plate, a pull rod disposed between the sliding rod and the connecting plate, a reset component disposed between the trigger rod and the inner wall of the square groove, and a side positioning component installed between the connecting plate and the fixed platform.
[0012] Furthermore, the reset component includes a reset plate disposed on the outer wall of the trigger rod and a reset spring disposed between the reset plate and the inner wall of the square groove.
[0013] Furthermore, the side positioning component includes a drive rod disposed on the side wall of the connecting plate, mounting grooves opened on the side walls on both sides of the fixed platform, two side positioning plates slidably disposed in the two mounting grooves, synchronization plates respectively disposed on the side walls of the two side positioning plates, and inclined grooves opened on the two synchronization plates, with the lower end of the drive rod located inside the inclined groove.
[0014] Furthermore, a housing is provided at the lower end of the fixed platform, and a mounting plate is provided at the lower end of the housing. The lower end of the support plate is fixedly connected to the upper end of the mounting plate.
[0015] Furthermore, the port of the feeding conveyor is located on one side above the electric gate, and the port of the discharging conveyor is located directly below the electric gate.
[0016] Furthermore, a circuit board testing method based on the maintenance of mass-energy equipment includes the following steps:
[0017] S1: Calibrate the voltage, current, and frequency parameters of the tester to ensure that the measurement accuracy meets the standards;
[0018] S2: Static testing of the power supply, grounding, and component parameters of the circuit board is performed using probes to verify whether they meet the design values;
[0019] S3: Place the circuit boards to be tested sequentially on the feeding conveyor to prepare for testing;
[0020] S4: The docking plate transports the circuit board on the feeding conveyor to the top of the electric gate. When the detection probe plate is descending, the automatic detection and fixing unit automatically positions and fixes the circuit board in the designated position. After fixing, the detection probe plate detects the circuit board.
[0021] S5: After the inspection is completed, the system determines whether the circuit board is damaged due to component pin problems, and based on the judgment result, the inspected circuit board is transferred to different positions through the discharge conveyor.
[0022] S6: Perform targeted repairs on circuit boards with identified component pin problems, and conduct further tests and make judgments on circuit boards with normal component pins.
[0023] Furthermore, the discharge conveyor is equipped with an electric guide baffle, which is electrically connected to the testing table. The electric guide baffle can guide two types of circuit boards, one with faulty component pins and the other with normal pins, to different directions for classification.
[0024] The beneficial effects of this invention are:
[0025] By setting up an automatic detection and fixing unit, this device can transfer the circuit board on the feeding conveyor to the fixed platform. When the detection probe plate moves downward, it can drive the docking plate to move horizontally through the trigger component. When the docking plate moves horizontally, it drives the circuit board to move simultaneously. Through the setting of the concave trigger plate, when the docking plate drives the circuit board to the front of the electric gate, the docking plate will quickly reset once, ensuring that the circuit board can be completely positioned directly above the electric gate. This avoids the situation where the circuit board cannot be positioned and clamped afterward because it is on the docking plate. At the same time, continuous detection of the circuit board can effectively improve the manufacturer's efficiency in repairing and testing the circuit board and reduce the time for circuit board repair and testing.
[0026] By setting up transmission components, when the docking plate moves horizontally for the second time, it can contact the side of the circuit board and drive the circuit board to move synchronously. At the same time, the side positioning plates on both sides, the side of the fixing platform, and the docking plate directly cooperate with each other to drive the circuit board to the designated point and fix the circuit board around its perimeter, which is convenient for subsequent probe detection. Therefore, by using transmission components, the circuit board is pushed to the designated point and the circuit board is fixed around its perimeter during probe detection.
[0027] By setting up a discharge conveyor and an electric guide baffle, after the inspection is completed, the electric guide baffle can classify and collect circuit boards with abnormal component pins and circuit boards with normal component pins. This makes it easier for staff to repair circuit boards with abnormal component pins and transfer circuit boards with normal component pins to the next process for other fault detection, which facilitates the subsequent repair of large batches of circuit boards.

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0043] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention, which provides a circuit board testing device based on the maintenance of mass-energy equipment, used to test circuit boards to be repaired. It includes a fixed platform 1, with two support plates 2 fixedly installed on the upper end of the fixed platform 1. A testing platform 3 is fixedly installed on the upper end of the two support plates 2. An automatic testing and fixing unit is installed between the fixed platform 1 and the testing platform 3. The automatic testing and fixing unit includes multiple limiting grooves 4 formed on both sides of the fixed platform 1, sliding rods 5 slidably installed in the multiple limiting grooves 4, docking plates 6 fixedly installed between the multiple sliding rods 5, and a testing mechanism installed at the lower end of the testing platform 3. An electric door 7 is installed at the bottom of the fixed platform 1; two support plates 8 are fixedly installed on one side of the fixed platform 1; a feeding conveyor 9 and a discharging conveyor 10 are installed between the two support plates 8; a triggering component is installed between the docking plate 6 and the detection mechanism; the docking plate 6 includes a first position and a second position. When the docking plate 6 is at the first position, it is used to connect the feeding conveyor 9 and the fixed platform 1; when the docking plate 6 moves from the first position to the second position, it is used to position the circuit board; when the docking plate 6 is at the second position, it is used to fix the circuit board.
[0044] The testing mechanism includes multiple telescopic rods 11 fixedly installed at the lower end of the testing platform 3, a testing probe plate 12 fixedly installed at the lower end of the multiple telescopic rods 11, an electric rod (not shown in the figure) set inside the testing platform 3, the telescopic end of the electric rod being fixedly connected to the telescopic rod 11, the testing probe plate 12 being located directly above the electric door 7, multiple long rods 29 fixedly installed at the lower end of the testing probe plate 12, multiple test plates 30 fixedly installed at the lower end of the multiple long rods 29, and multiple test probes 31 fixedly installed at the lower end of the test plates 30.
[0045] A housing 27 is fixedly installed at the lower end of the fixed platform 1, and a mounting plate 28 is fixedly installed at the lower end of the housing 27. The lower end of the bearing plate 8 is fixedly connected to the upper end of the mounting plate 28. The port of the feeding conveyor 9 is located on one side above the electric gate 7, and the port of the discharging conveyor 10 is located directly below the electric gate 7.
[0046] Specifically, the fixed platform 1 is used to place the circuit board to be tested. The principle of the testing platform 3 to test the circuit board is as follows: the test probe 31 at the lower end contacts the pin area on the circuit board and applies a certain voltage to determine whether the circuit board is damaged due to the pin damage of the circuit board components. The testing platform 3 drives the test probe 31 at the lower end of the test board 30 to move downward and contact the upper end of the circuit board through the telescopic end of the electric rod to test the circuit board. At the same time, the test results are transmitted to the terminal for data analysis.
[0047] By setting up the docking plate 6, which is installed on the fixed platform 1 at a certain tilt angle, when the docking plate 6 is in the initial position, the docking plate 6 is equivalent to the bridge between the feeding conveyor 9 and the fixed platform 1. When the feeding conveyor 9 slowly transports the circuit board to the end, the circuit board falls onto the docking plate 6 under the action of inertia and waits for the circuit board to be tested.
[0048] By setting up an automatic detection and fixing unit, the circuit board can be automatically positioned and fixed in a designated area on the fixing platform 1 during the downward movement of the detection probe plate 12 (the designated area of the fixing platform 1 is set directly above the electric door 7, that is, when the circuit board is in the designated area, the test probe 31 can be aligned with the pins on the circuit board when it moves downward, and can be directly tested). The whole process is automated and continuous, which allows manufacturers to continuously repair and test multiple circuit boards, effectively improving the manufacturer's repair and testing of circuit boards. There is no need for manual fixing of the circuit board, which effectively improves the testing efficiency.
[0049] The feeding conveyor 9 is used to transport the circuit board to the fixed table 1. The electric door 7 is electrically connected to the inspection table 3. Whenever the inspection table 3 inspects the circuit board, it sends a control signal to control the electric door 7 to open and close once. Therefore, whenever the inspection table 3 finishes inspecting the circuit board on the electric door 7, the electric door 7 automatically opens and the circuit board falls onto the discharge conveyor 10 under the action of gravity. The discharge conveyor 10 can transport the circuit board to the next process, thereby completing the continuity of the circuit board inspection.
[0050] Example 2, refer to Figures 5-12 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the triggering component includes an extension plate 13 fixedly installed on the side wall of the detection probe plate 12, a concave trigger plate 14 fixedly installed at the lower end of the extension plate 13, square grooves 15 opened on the side walls of the two support plates 2, two mounting shafts 16 fixedly installed on the inner walls of the two square grooves 15, and a V-shaped mating plate 17 rotatably installed on the two mounting shafts 16. A transmission element is installed between the V-shaped mating plate 17 and the corresponding sliding rod 5.
[0051] The transmission components include a trigger rod 18 slidably mounted inside the two support plates 2, one end of which is hinged to a V-shaped mating plate 17; a connecting plate 19 fixedly mounted at the end of the trigger rod 18 away from the V-shaped mating plate 17; a pull rod 20 fixedly mounted between the sliding rod 5 and the connecting plate 19; a reset component installed between the trigger rod 18 and the inner wall of the square groove 15; and a side positioning component installed between the connecting plate 19 and the fixed platform 1. The reset component includes a reset plate 21 fixedly mounted on the outer wall of the trigger rod 18 and a reset spring 22 fixedly mounted between the reset plate 21 and the inner wall of the square groove 15.
[0052] The side positioning component includes a drive rod 23 fixedly installed on the side wall of the connecting plate 19, mounting slots opened on the side walls of both sides of the fixed platform 1, two side positioning plates 24 slidably installed in the two mounting slots, synchronization plates 25 fixedly installed on the side walls of the two side positioning plates 24 respectively, and inclined slots 26 opened on the two synchronization plates 25. The lower end of the drive rod 23 is located inside the inclined slot 26.
[0053] Specifically, the V-shaped mating plate 17 is made of shape memory plastic. The triggering component works as follows: during the downward movement of the detection probe plate 12 to detect the circuit board, the detection probe plate 12 moves synchronously through the concave trigger plate 14 at the lower end of the extension plate 13. During the downward movement of the concave trigger plate 14, it causes the V-shaped mating plate 17 to be squeezed inward, causing the V-shaped mating plate 17 to deform downward. During the deformation, the trigger rod 18 moves horizontally. During the movement, the trigger rod 18 can pull the mating plate 6 to move horizontally synchronously through the pull rod 20. When the mating plate 6 moves horizontally, one end of it can push the circuit board to move synchronously.
[0054] When the docking plate 6 moves to its maximum distance, the distance between one end of the docking plate 6 and the side wall of the fixed stage 1 is equal to the width of the circuit board. The shortest distance between the two side positioning plates 24 after they move is equal to the length of the circuit board. At the same time, when the docking plate 6 moves to its maximum distance, it drives the two side positioning plates 24 to move to their maximum distance through the side positioning components. At this time, one end of the docking plate 6, the side wall of the fixed stage 1, and the two side positioning plates 24 cooperate with each other to position and fix the circuit board, preventing the circuit board from not being aligned with the test probe 31 during the testing process, and improving the stability of the circuit board during testing.
[0055] The purpose of setting the concave trigger plate 14 to be concave is as follows: During the downward movement of the concave trigger plate 14, its lower end will drive the docking plate 6 to reach the maximum distance for the first time. At this time, if the docking plate 6 continues to move downward, it will quickly reset under the action of the reset spring 22. Even if the circuit board is above the docking plate 6, making it impossible for one end of the docking plate 6 to align with one end of the circuit board, the circuit board above it can be separated from the docking plate 6 by the action of inertia through the rapid reset of the docking plate 6. In this way, when the docking plate 6 makes a second movement, one end of the docking plate 6 can push one end of the circuit board to move during the movement, and cooperate with the side wall of the fixed platform 1 and the two side positioning plates 24 to position and fix the circuit board.
[0056] During use, when the circuit board is above the docking plate 6 or the fixed platform 1, the electric lever is activated, causing the detection probe plate 12 to move downwards. As the detection probe plate 12 moves downwards, it causes the concave trigger plate 14 to move downwards synchronously. When the concave trigger plate 14 moves downwards, its lowest point contacts the V-shaped mating plate 17, causing the V-shaped mating plate 17 to deform inwards. During this deformation, the trigger rod 18 and the pull rod 20 drive the docking plate 6 to move horizontally, thus causing the docking plate 6 to move horizontally for the first time. During this first movement, the circuit board above or to one side of the docking plate 6 can be moved above the electric door 7. When the middle recess of the concave trigger plate 14 is located at the V-shaped mating plate 17... The V-shaped mating plate 17 quickly resets, causing the mating plate 6 to reset quickly as well. The purpose of resetting the mating plate 6 once is to prevent the circuit board from being unable to be fixed in place by simple horizontal movement of the mating plate 6 when it is above it. Therefore, when the mating plate 6 resets, the circuit board above it can separate from the mating plate 6 under the action of inertia. This allows the mating plate 6 to push the circuit board during its second horizontal movement. Since the distance between one end of the mating plate 6 and the side wall of the fixed platform 1 is equal to the width of the circuit board, when the mating plate 6 moves to its maximum distance, the mating plate 6 and the side wall of the fixed platform 1 cooperate with each other to fix the width of the circuit board.
[0057] When the docking plate 6 moves horizontally, its drive rod 23 moves horizontally synchronously with the connecting plate 19. During the horizontal movement of the connecting plate 19, the lower end of the drive rod 23 cooperates with the inclined groove 26, and the synchronous plate 25 drives the side positioning plates 24 on both sides to move towards each other synchronously. During the movement, the two side positioning plates 24 cooperate to fix the two sides of the circuit board in the length direction. After the docking plate 6 fixes the width direction of the circuit board, the two side positioning plates 24 can fix and position the circuit board in the length direction, thereby completing the automated positioning and fixing of the circuit board, which is convenient for subsequent testing.
[0058] The remaining structure is the same as that in Example 1.
[0059] Example 3, referring to Figure 3 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that an electric guide baffle (not shown in the figure) is installed on the discharge conveyor 10. The electric guide baffle is electrically connected to the detection table 3. The electric guide baffle can guide the two types of circuit boards with faulty component pins and normal ones to different directions for classification.
[0060] Specifically, the electric guide baffle is used to change the direction of the discharge conveyor 10 when transporting circuit boards. With this setting, after the circuit board is inspected, the back-end can use the inspection data to determine whether the circuit board is faulty due to damaged component pins. The electric guide baffle can process the circuit boards in batches, collect the circuit boards with damaged component pins, and facilitate the manufacturer to carry out targeted repairs on these faulty circuit boards. The circuit boards with normal component pins are guided to another direction to carry out other tests on the circuit boards to determine the cause of the damage and subsequent repairs.
[0061] The remaining structure is the same as that in Example 2.
[0062] Example 4, refer to Figures 1-12 The fourth embodiment of the present invention provides a circuit board testing method based on the maintenance of mass-energy equipment, comprising the following steps:
[0063] S1: Calibrate the voltage, current, and frequency parameters of the tester to ensure that the measurement accuracy meets the standards.
[0064] S2: Static tests are performed on the power supply, grounding, and component parameters of the circuit board using probes to verify whether they meet the design values.
[0065] S3: Place the circuit boards to be tested sequentially on the feeding conveyor 9 to prepare for testing.
[0066] S4: When the circuit board is above the docking plate 6 or the fixed platform 1, the electric lever is activated, and the drive end drives the detection probe plate 12 to move downward. When the detection probe plate 12 moves downward, it will drive the concave trigger plate 14 to move downward synchronously. When the concave trigger plate 14 moves downward, its lowest end contacts the V-shaped mating plate 17 and deforms the V-shaped mating plate 17 inward. During the deformation process, the trigger rod 18 and the pull rod 20 drive the docking plate 6 to move horizontally, thereby driving the docking plate 6 to move horizontally for the first time. During the first movement, the docking plate 6 can drive the circuit board above or on one side of the docking plate 6 to enter the area above the electric door 7. When the middle concave position of the concave trigger plate 14 is located at the V-shaped mating plate 17... The V-shaped mating plate 17 quickly resets, causing the mating plate 6 to reset quickly as well. The purpose of resetting the mating plate 6 once is to prevent the circuit board from being unable to be fixed in place by simple horizontal movement of the mating plate 6 when it is above it. Therefore, when the mating plate 6 resets, the circuit board above it can separate from the mating plate 6 under the action of inertia. This allows the mating plate 6 to push the circuit board during its second horizontal movement. Since the distance between one end of the mating plate 6 and the side wall of the fixed platform 1 is equal to the width of the circuit board, when the mating plate 6 moves to its maximum distance, the mating plate 6 and the side wall of the fixed platform 1 cooperate with each other to fix the width of the circuit board.
[0067] When the docking plate 6 moves horizontally, its drive rod 23 moves horizontally synchronously with the connecting plate 19. During the horizontal movement of the connecting plate 19, the lower end of the drive rod 23 cooperates with the inclined groove 26, and the synchronous plate 25 drives the side positioning plates 24 on both sides to move towards each other synchronously. During the movement, the two side positioning plates 24 cooperate to fix the two sides of the circuit board in the length direction. After the docking plate 6 fixes the width direction of the circuit board, the two side positioning plates 24 can fix and position the circuit board in the length direction, thereby completing the automated positioning and fixing of the circuit board, which is convenient for subsequent testing.
[0068] S5: After the inspection is completed, the system determines whether the circuit board is damaged due to component pin problems, and based on the judgment result, the inspected circuit board is transferred to different positions through the discharge conveyor 10.
[0069] S6: Perform targeted repairs on circuit boards with identified component pin problems, and conduct further tests and make judgments on circuit boards with normal component pins.
[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
