Description

Technical Field

[0001] The invention relates to the technical field of battery vehicle controller detection, and in particular to a battery vehicle controller sealing resistance detection device. Background Art

[0002] The battery car controller is the core component of the battery car's electric system, mainly used to control the speed of the motor and various operating instructions of the battery car. It is like the brain of the battery car, responsible for coordinating the work of the battery, motor and other electronic components to ensure that the battery car can start, run, advance and retreat, adjust speed, stop and other operations according to the driver's intention.

[0003] Therefore, during production, the battery vehicle controller has high requirements for sealing and resistance, to prevent collision deformation or water ingress during use, thereby affecting the use of internal electronic components. However, existing testing equipment cannot perform integrated testing for sealing and resistance, and needs to be tested separately, resulting in low testing efficiency.

[0004] Therefore, it is necessary to provide a battery vehicle controller sealing resistance detection device, which can integrate sealing and resistance into one during detection to improve detection efficiency. Summary of the invention

[0005] The object of the present invention is to provide a battery vehicle controller sealing resistance detection device to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a battery vehicle controller sealing resistance detection device, comprising a lower shell, a support frame fixed on the lower shell and a protective plate wrapped around the outside of the support frame, wherein: Conveyor belts are fixed on the left and right sides of the top of the lower housing, and a battery vehicle controller is arranged on each set of conveyor belts; It also includes a moving mechanism arranged on the support frame, which is used to drive the battery vehicle controller on the conveyor belt to move; A sealing detection mechanism disposed on the top of the lower housing is used to detect the sealing and resistance of the battery vehicle controller; A pipeline transmission mechanism disposed in the lower housing, used for transmitting liquid to the sealing detection mechanism; The sealing detection mechanism includes a detection box fixed on the lower housing, a cover assembly arranged on one side of the detection box and a clamping assembly arranged inside the detection box, wherein the cover assembly is used to form the detection box into a sealed state, and the clamping assembly is used to clamp the battery vehicle controller, wherein: The clamping assembly includes four groups of fifth drives fixed in the detection box, the output end of the fifth drive is fixed with a clamping plate, and the inside of the detection box is fixed with a liquid level sensor for detecting the liquid level height in the detection box; The pipeline transmission mechanism includes a water tank fixed inside the lower outer shell, and the outer pipeline of the water tank is connected to three groups of transmission pipes, and the ends of the three groups of transmission pipes are fixed with a central pipe, and four groups of branch pipes are connected to the central pipe. The other end of the branch pipe is fixedly connected to the detection box, each group of the transmission pipes is connected to a first pump body, and each group of the branch pipes is connected to a first valve.

[0007] A battery vehicle controller sealing resistance detection device, and also includes a battery vehicle controller sealing judgment method: Method 1: The staff sets the normal liquid level height as h in the controller, and the liquid level detected by the liquid level sensor is transmitted to the controller in real time, and compared with the set liquid level height h to determine whether there is leakage in the battery vehicle controller at the moment; Method 2: When there is no leakage in the battery vehicle controller, it is necessary to further extend the soaking time to the set time. If the liquid level changes within the specified time, it means that there is a gap in the battery vehicle controller. If the liquid level does not change within the specified time, it means that there is no gap in the battery vehicle controller. According to the above technical solution, the second method also includes the following specific steps: Method 2-a: Control the fifth drive to extend a certain distance through the controller, so as to drive the clamping plate to clamp the electric controller; Method 2-b: When the electric controller is squeezed, the liquid level sensor again detects the liquid height in the test box in real time. If the liquid height becomes lower than the set height, it means that the battery vehicle controller is squeezed and cracks are generated, causing liquid to enter the battery vehicle controller. At this time, the signal is transmitted to the controller to mark the battery vehicle controller so that the cracks can be repaired later.

[0008] According to the above technical solution, after the sealing test is completed, the liquid in the test box needs to be sucked away to further analyze the deformation degree of the surface of the battery vehicle controller, including the following analysis steps: Step 1: After the battery vehicle controller in the first detection box is tested, the controller controls the first group of second pump bodies, the first group of first valves and the second group of first valves to start, so that the liquid in the first detection box is transferred to the central tube through the first group of branch pipes, and then into the second detection box through the second branch pipe; Step 2: At this time, there is no liquid in the first detection box, which makes it easy for the camera to take pictures of the outside of the battery vehicle controller and transmit them to the controller. The controller analyzes whether the pictures are deformed. If there is no obvious change on the outside of the battery vehicle controller, it means that the battery vehicle controller has good resistance. If the outside of the battery vehicle controller is deformed, it means that the battery vehicle controller cannot return to its original state when squeezed again, which means that the battery vehicle controller has poor resistance.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention, by providing a clamping assembly and a pipeline transmission mechanism, can detect the sealing and resistance of the electric vehicle controller, ensure the quality of the electric vehicle controller produced, and combine the sealing and resistance into one, thereby improving the detection efficiency.

DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0012] See also Figure 1-7 The present invention provides a technical solution: a battery vehicle controller sealing resistance detection device, including a lower shell 4, a support frame 18 fixed on the lower shell 4 and a protective plate 1 included on the outside of the support frame 18.

[0013] Conveyor belts 2 are fixed on the left and right sides of the top of the lower housing 4, and a battery vehicle controller is arranged on each group of conveyor belts 2.

[0014] The moving mechanism arranged on the support frame 18 is used to drive the electric vehicle controller on the conveyor belt 2 to move. The sealing detection mechanism arranged on the top of the lower shell 4 is used to detect the sealing and resistance of the electric vehicle controller. The pipeline transmission mechanism arranged in the lower shell 4 is used to transmit the liquid to the sealing detection mechanism.

[0015] The moving mechanism includes a thread transmission component and an adsorption component, the thread transmission component is used to drive the adsorption component to move, and the adsorption component is used to adsorb the battery vehicle controller on the conveyor belt 2; The thread transmission component includes two groups of sliding rods 10 fixed on the support frame 18, and threaded rods 19 fixed on the support frame 18. The threaded rods 19 are arranged on one side of one group of sliding rods 10. A first drive 17 is fixed on the support frame 18. The output end of the first drive 17 is fixedly connected to the threaded rods 19. A slider 12 is slidably connected to each group of sliding rods 10, and one group of sliders 12 is threadedly connected to the threaded rods 19. Starting the first drive 17 drives the threaded rods 19 to rotate, thereby driving the slider 12 to move on the sliding rod 10. When the slider 12 moves, it drives the adsorption component to move horizontally.

[0016] It should be noted that the first drive 17 may be a motor.

[0017] The adsorption component includes a fixed plate 13 fixed on its slider 12, two groups of sliding rods 2 15 are fixed on the two groups of fixed plates 13, and sliding rods 2 16 are slidably connected to the two groups of sliding rods 2 15. The fixed plate 13 is provided with a second drive 14, the output end of the second drive 14 is fixedly connected to the fixed plate 13, the shell of the second drive 14 is fixedly connected to the sliding rod 2 16, the bottom of the sliding rod 2 16 is fixed with a third drive 20, and the output end of the third drive 20 is fixed with an electromagnetic suction cup 21. Starting the second drive 14 can drive the sliding rod 2 16 to move back and forth longitudinally on the sliding rod 2 15, thereby driving the electromagnetic suction cup 21 to move back and forth longitudinally. When the electromagnetic suction cup 21 needs to be used, the third drive 20 is controlled to extend, so that the electromagnetic suction cup 21 moves longitudinally and contacts with the surface of the battery vehicle controller, so as to adsorb the battery vehicle controller.

[0018] Specifically, when the electric vehicle controller needs to be moved, the staff places the electric vehicle controller on the conveyor belt 2, transports the electric vehicle controller to the inside of the protective plate 1, drives the adsorption component to move to the electric vehicle controller by starting the threaded transmission component, starts the third drive 20 to move the electromagnetic suction cup 21 downward to adsorb the electric vehicle controller, and then controls the third drive 20 to move upward to drive the electric vehicle controller away from the conveyor belt 2. At this time, the second drive 14 is started to drive the electric vehicle controller to move to the top of the detection mechanism, and then the third drive 20 is controlled to extend, and the electric vehicle controller is driven to enter the detection mechanism through the electromagnetic suction cup 21, so as to facilitate the subsequent sealing detection of the electric vehicle controller.

[0019] It should be added that, after the first battery vehicle controller is placed, the above steps are repeated to place the second battery vehicle controller until battery vehicle controllers are placed in all the detection boxes 9 .

[0020] It should be noted that the second drive 14 may be an electric telescopic rod, and the third drive 20 may be a cylinder.

[0021] The sealing detection mechanism includes a detection box 9 fixed on the lower shell 4, a cover assembly arranged on one side of the detection box 9 and a clamping assembly arranged inside the detection box 9. The cover assembly is used to form the detection box 9 into a sealed state, and the clamping assembly is used to clamp the battery vehicle controller.

[0022] Four groups of detection boxes 9 are provided, and four groups of cover plate assemblies are provided. One side of each group of detection boxes 9 is matched with a cover plate assembly. The cover plate assembly includes a cover plate 11 hinged on the detection box 9, and a fourth drive 22 fixed on the lower shell 4. A connecting plate 23 is hinged on the fourth drive 22. The connecting plate 23 is fixedly connected to the cover plate 11. A camera (not shown in the figure) is fixed to the bottom of the cover plate 11. The fourth drive 22 is started to extend and push the connecting plate 23 to move, thereby driving the cover plate 11 to swing around one side of the detection box 9 and covering the cover plate 11 on the detection box 9.

[0023] The clamping assembly includes four groups of fifth drives 25 fixed in the detection box 9. The output end of the fifth drive 25 is fixed with a clamping plate 26. The inside of the detection box 9 is fixed with a liquid level sensor 27 and a turbidity detector 30 for detecting the liquid level height in the detection box 9.

[0024] It should be noted that the fourth drive 22 and the fifth drive 25 may be cylinders.

[0025] Specifically, when the battery vehicle controller is placed into the testing box 9, the fifth drive 25 is started to extend, and the battery vehicle controller is clamped around to fix the battery vehicle controller. After the battery vehicle controller is fixed, the cover assembly is started to cover the cover 11 on the testing box 9, so that the liquid will not jump out during the subsequent testing of the sealing and resistance of the battery vehicle controller.

[0026] The pipeline transmission mechanism includes a water tank 5 fixed inside the lower outer shell 4, and the outer pipeline of the water tank 5 is connected to three groups of transmission pipes 6. The ends of the three groups of transmission pipes 6 are fixed with a central pipe 8, and four groups of branch pipes 28 are connected to the central pipe 8. The other ends of the branch pipes 28 are fixedly connected to the detection box 9. Each group of transmission pipes 6 is connected to a first pump body 7, and each group of branch pipes 28 is connected to a first valve 24. The central pipe 8 is connected to three groups of second pump bodies 29, and each group of second pump bodies 29 is arranged between two groups of first valves 24.

[0027] It should be noted that the first pump body 7 and the second pump body 29 are liquid pumps.

[0028] The controller 3 is fixed to the outside of the protection plate 1, and the first pump body 7, the second pump body 29, the camera, the turbidity detector 30, the first valve 24 and the liquid level sensor 27 are electrically connected.

[0029] Specifically, when it is necessary to test the sealing and resistance of the battery vehicle controller, the battery vehicle controller is clamped by the clamping assembly. At this time, the first pump body 7 is started to pump the liquid in the water tank 5 into the central tube 8 through the transmission pipe 6, and then transmitted to the detection box 9 through the branch pipe 28 until it is not on the battery vehicle controller, and the sealing and resistance of the battery vehicle controller are started to be tested.

[0030] The liquid level in the detection box 9 is monitored by the liquid level sensor 27, and the signal is transmitted to the controller 3. By judging the change of the liquid level, it is analyzed whether the battery vehicle controller is sealed. The specific method of judging is: The staff sets the normal liquid level height as h in the controller 3, and the liquid level detected by the liquid level sensor 27 in real time is transmitted to the controller 3, and compared with the set liquid level height h to determine whether there is leakage in the battery vehicle controller at present. If it remains unchanged from the set height, it means that the battery vehicle controller is not leaking at present. If it is lower than the set height, it means that the sealing of the battery vehicle controller is poor. At this time, the signal is transmitted to the controller 3 to alarm, which is convenient for the staff to handle.

[0031] Furthermore, when there is no leakage in the battery vehicle controller at the moment, it is necessary to further extend the immersion time to the set time. If the liquid level changes within the specified time, it means that there is a gap in the battery vehicle controller, and the liquid slowly penetrates into the inside of the battery vehicle controller, so the liquid level becomes lower. At this time, a signal is transmitted to the controller 3 to alarm. If the liquid level does not change within the specified time, it means that there is no gap in the battery vehicle controller. At this time, the fifth drive 25 is controlled by the controller 3 to extend a certain distance, driving the clamping plate 26 to clamp the electric controller. When the electric controller is squeezed, the liquid level sensor 27 again detects the liquid height in the detection box 9 in real time. If the liquid height is lower than the set height, it means that the battery vehicle controller is squeezed and cracks are generated, causing liquid to enter the battery vehicle controller. At this time, a signal is transmitted to the controller to mark the battery vehicle controller, and the cracks can be repaired later. Through this step, the sealing of the battery vehicle can be accurately detected, thereby ensuring the detection efficiency of the sealing of the battery vehicle controller.

[0032] After the sealing test is completed, it is necessary to suck out the liquid in the test box 9 to further analyze the deformation degree of the surface of the battery vehicle controller. It should be added that after the battery vehicle controller in the first group of test boxes 9 is tested, the first group of second pump bodies 29 and the first and second groups of first valves 24 are started by the controller 3 to transfer the liquid in the first group of test boxes 9 to the central tube 8 through the first group of branch pipes 28, and then pass into the second test box 9 along the second branch pipe 28. At this time, there is no liquid in the first test box 9, which is convenient for the camera to take pictures of the outside of the battery vehicle controller and transmit them to the controller 3. The controller 3 analyzes whether the picture is deformed. If there is no obvious change on the outside of the battery vehicle controller, it means that the battery vehicle controller has good resistance. If the outside of the battery vehicle controller is deformed, it means that the battery vehicle controller fails to return to its original state when squeezed again, which means that the battery vehicle controller has poor resistance.

[0033] Through the above steps, the sealing and resistance of the battery vehicle controller can be tested to ensure the quality of the battery vehicle controller, and the sealing and resistance can be integrated into one to improve the detection efficiency.

[0034] It should be noted that when the resistance of the battery vehicle controller is tested in the first group of test boxes 9, the sealing of the battery vehicle controller is continued to be tested in the second test box 9. After the sealing test of the battery vehicle controller in the second test box 9 is completed, the liquid in the second test box 9 is transferred to the third test box 9, and the resistance test step of the battery vehicle controller in the second test box 9 is repeated. This process is repeated until the battery vehicle controller in the fourth group of test boxes 9 is tested. By means of this alternating and sequential testing step, liquid can be saved.

[0035] It should be added that when liquid is lost during transmission between the detection boxes 9, the first pump body 7 can be opened to pump the liquid in the water storage tank 5 into the detection box 9 where the liquid is lost, so that the liquid reaches the set liquid level height h.

[0036] When the liquid is in the detection box 9, the impurities in the battery vehicle controller in the detection box 9 can be cleaned at the same time. When the liquid is transmitted in the detection box 9 one by one, the impurities in the previous detection box 9 can be taken away. The turbidity detector 30 in the detection box 9 detects the turbidity change of the liquid in real time. Since the staff sets the maximum turbidity value in the controller 3, when the liquid reaches the maximum turbidity in the first two groups of detection boxes 9, it means that there are many impurities in the battery vehicle controller. When the liquid reaches the maximum turbidity in the last two groups of detection boxes 9, it means that the impurity level of the battery vehicle controller is normal. The turbidity of the liquid can be transmitted to the controller 3, which is convenient for the staff to replace the detection liquid in real time to ensure the cleanliness of the battery vehicle controller during detection.

[0037] Through the above steps, when testing the sealing and resistance of the battery vehicle controller, the turbidity of the liquid can also be judged to ensure the cleanliness of the battery vehicle controller.
