Description

Technical Field

[0001] This utility model relates to the field of control board testing technology, and in particular to a testing device for power control boards. Background Technology

[0002] With the development of new energy technologies, the number of new energy vehicles is increasing year by year. Some car owners will install AC charging piles in their parking spaces. AC charging piles need to rectify the mains power through the power control board before sending it to the vehicle for charging. At the same time, the power control board detects the temperature parameters in the charger to ensure charging safety. Therefore, the reliability of the power control board is crucial to charging safety. For this reason, the power control board needs to be fully inspected before leaving the factory. To improve testing speed, various testing devices have been designed. For example, Chinese Patent Application No. 202222117154.1 discloses a testing device for power control board production, including a control box. A support platform is installed on the top of the control box, and a testing platform is placed on the top of the support platform. A movable hole is opened on the top of the support platform, and a movable rod is slidably installed in the movable hole. The top end of the movable rod is fixedly connected to the testing platform. The bottom ends of multiple movable rods are equipped with the same drive plate. A drive mechanism is installed inside the control box and connected to the drive plate. A sliding hole is opened on the top of the support platform, and a sliding plate is slidably installed in the sliding hole. A pressure plate is fixedly installed on the top of the sliding plate. Two rectangular holes are opened on the support platform, and a movable mechanism is installed in the rectangular holes. This device uses a motor to drive a screw, which can fix the power control board on the test platform, preventing the power control board from becoming loose during testing. However, during testing, it is still necessary to manually use tools such as multimeters to test the test points on the power control board, resulting in low testing efficiency. Therefore, a power control board testing device is needed that can fix the power control board while also extending probes to the test points on the power control board, enabling rapid testing of the power control board. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a power control board testing device that, while fixing the power control board, can also extend probes to the testing points of the power control board, enabling rapid testing of the power control board.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a testing device for a power control board, comprising: an operating table, a fixed mold, lifting columns, a pressing component, and a probe assembly. The operating table has supporting feet at its lower part. The fixed mold is bolted to the middle of the upper surface of the operating table. There are four lifting columns. Four guide sleeves are provided on the outer sides of the four corners of the fixed mold. The lifting columns pass through the guide sleeves.

A guide rail is provided between the connecting plates. The probe assembly is mounted on the guide rail. The upper part of the lifting column has external threads. The pressing component is fixed to the upper part of the lifting column by nuts.

[0006] Furthermore, the pressing assembly includes a sleeve, a fixed rod, and a swing rod. The sleeve is fitted onto the lifting column. The fixed rod radially fixes the upper part of the outer side of the sleeve. One end of the swing rod is hinged to the lower part of the outer side of the sleeve. The other end of the swing rod is provided with a pressing column. A first spring is provided between the middle of the swing rod and the fixed rod.

[0007] Furthermore, a silicone pad is provided at the lower end of the pressure column.

[0008] Furthermore, the probe assembly includes a slider, a spring cylinder, and a probe. The slider is slidably connected to the guide rail, the spring cylinder is installed at the lower part of the slider, the probe passes through the spring cylinder and the slider, and the middle part of the probe is connected to the slider through a second spring, which is installed in the middle of the spring cylinder.

[0009] Furthermore, the slider is provided with a locking bolt, the end of which passes through the slider and is pressed tightly against the guide rail.

[0010] Furthermore, the connecting plate is provided with a sliding groove, and the two ends of the guide rail are connected to the sliding groove by bolts, with the sliding groove and the guide rail being perpendicular to each other.

[0011] Furthermore, one or more guide rails are mounted on the sliding groove, and two or more probe assemblies are mounted on the guide rails.

[0012] Furthermore, the lower part of the operating platform is provided with an electric telescopic rod, the main body of which is connected to the operating platform, and the telescopic end of which is connected to the lifting plate.

[0013] Furthermore, a limiting nut is provided in the middle of the lifting column.

[0014] The beneficial effects of this utility model are as follows: After the lifting column is lowered by the electric telescopic rod, the power control board on the fixed mold is first pressed by the lowering column. Then the probe assembly continues to descend, so that the probe contacts the detection point on the power control board and realizes electrical connection. This makes it convenient for the testing instrument to connect to the power control board, thereby replacing manual detection at the detection point and improving the detection speed of the power control board.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0022] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0023] like Figures 1 to 4 As shown, an embodiment of this utility model provides a testing device for a power control board, including: an operating table 1, a fixed mold 2, lifting columns 3, a pressing component 4, and a probe component 5. The operating table 1 is provided with supporting feet 6 at its lower part. The fixed mold 2 is installed in the middle of the upper surface of the operating table 1 by bolts. There are four lifting columns 3. Four guide sleeves 7 are provided on the outer side of the four corners of the fixed mold 2. The lifting columns 3 pass through the guide sleeves 7. The lower ends of the lifting columns 3 are connected to each other by lifting plates 8. The upper ends of the lifting columns 3 on the same side are connected to each other by connecting plates 9. A guide rail 10 is provided between the connecting plates 9. The probe component 5 is installed on the guide rail 10. The upper part of the lifting column 3 is provided with external threads. The pressing component 4 is fixed to the upper part of the lifting column 3 by nuts.

[0024] The fixed mold 2 has a groove. When testing the power control board, the worker places the power control board to be tested on the fixed mold 2, and then starts the testing device. After the electric telescopic rod 22 extends, it drives the lifting plate 8 and the lifting column 3 to move down, causing the pressing component 4 and the probe component 5 on the lifting column 3 to move down. The pressing column 14 on the pressing component 4 is lower than the probe 18. As a result, the pressing column 14 contacts the power control board first. Then the lifting column 3 continues to descend, thereby moving the swing rod 13 up. The fixed rod 12 pushes the swing rod 13 through the first spring 15, so that the swing rod 13 moves down. Column 14 presses down on the power control board to prevent it from shifting. After the lifting column 3 continues to descend, the lower end of probe 18 contacts the detection point on the power control board, making probe 18 electrically connected to the power control board. After the testing instrument is connected to probe 18 through wires, it can detect various parameters of the power control board, thereby determining whether the power control board is working properly. The position of probe assembly 5 can be adjusted by sliding groove 21 and guide rail 10 to meet the needs of rapid connection of different detection points of different power control boards. Compared with manual testing one by one, this device can greatly improve the testing speed.

[0025] In a specific embodiment, such as Figure 3 As shown, the pressing assembly 4 includes a sleeve 11, a fixed rod 12, and a swing rod 13. The sleeve 11 is fitted onto the lifting column 3. The fixed rod 12 is radially fixed to the upper part of the outer side of the sleeve 11. One end of the swing rod 13 is hinged to the lower part of the outer side of the sleeve 11. The other end of the swing rod 13 is provided with a pressing column 14. A first spring 15 is provided between the middle of the swing rod 13 and the fixed rod 12. The pressing assembly 4 can be adjusted in position and direction on the lifting column 3 by means of a nut, so that the swing rod 13 can better apply downward pressure to the power control board, thereby positioning the power control board by means of the fixed mold 2, so that the probe 18 can accurately contact the detection point on the power control board.

[0026] Specifically, a silicone pad is provided at the lower end of the pressure column 14. The silicone pad is insulating and soft, and when pressed against the upper part of the power control board, it can avoid damaging the components on the power control board and ensure the smooth progress of the test.

[0027] In a specific embodiment, such as Figure 4 As shown, the probe assembly 5 includes a slider 16, a spring cylinder 17, and a probe 18. The slider 16 is slidably connected to the guide rail 10. The spring cylinder 17 is installed at the lower part of the slider 16. The probe 18 passes through the spring cylinder 17 and the slider 16. The middle part of the probe 18 is connected to the slider 16 through a second spring 19. The second spring 19 is installed in the middle of the spring cylinder 17. The slider 16 and the spring cylinder 17 can ensure that the probe 18 can only move along the axis so that the probe 18 can accurately contact the detection point on the power control board. The second spring 19 can provide elasticity and provide downward pressure when the probe 18 contacts the detection point, ensuring good electrical connection while avoiding damage to the probe 18 and the power control board.

[0028] Specifically, the slider 16 is provided with a locking bolt 20. The end of the locking bolt 20 passes through the slider 16 and presses tightly onto the guide rail 10. After the slider 16 slides on the guide rail 10, the locking bolt 20 can lock the slider 16 to prevent the probe assembly 5 from shifting during detection.

[0029] Preferably, such as Figure 2 As shown, the connecting plate 9 is provided with a sliding groove 21. The two ends of the guide rail 10 are connected to the sliding groove 21 by bolts. The sliding groove 21 and the guide rail 10 are perpendicular to each other. The sliding groove 21 and the guide rail 10 can adjust the position of the probe assembly 5 in the horizontal direction, so that the probe assembly 5 can be locked above the detection point. After pressing down, the probe 18 can make good contact with the detection point.

[0030] In one specific embodiment, one or more guide rails 10 are installed on the sliding groove 21, and two or more probe assemblies 5 are installed on the guide rails 10, so that after the lifting column 3 descends, multiple probes 18 can simultaneously contact multiple detection points to achieve rapid detection.

[0031] In one specific embodiment, the lower part of the operating table 1 is provided with an electric telescopic rod 22. The main body of the electric telescopic rod 22 is connected to the operating table 1, and the telescopic end of the electric telescopic rod 22 is connected to the lifting plate 8. The electric telescopic rod 22 can provide downward pressure, and drive the lifting column 3 to move downward through the lifting plate 8 to realize the fixing and detection operation of the power control board.

[0032] In a preferred embodiment, a limiting nut 23 is provided in the middle of the lifting column 3. The limiting nut 23 can limit the position of the lifting column 3 to prevent the lifting column 3 from falling too low and causing damage to the probe 18 and the power control board.

[0033] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
