[0002] Battery modules are the power batteries for electric vehicles. Battery modules typically use liquid cooling plates to cool the cells. Currently, insulation withstand voltage testing is a technical means to inspect and evaluate the insulation withstand voltage capability of liquid cooling plates. Insulation withstand voltage testing is a test conducted using a withstand voltage tester to test the voltage withstand capability of the insulating material on the surface of the liquid cooling plate. The process of applying a high voltage to the insulating material without damaging its performance is called withstand voltage testing. Generally speaking, the main purpose of withstand voltage testing is to check the insulation's ability to withstand working voltage or overvoltage, and thus verify whether the insulation performance meets safety standards.
[0003] During the withstand voltage test, the liquid cooling plate is fixed on the panel. The bottom of the pressure plate above the panel is covered with conductive cotton to make contact with the area of the liquid cooling plate that needs to be tested for insulation withstand voltage. In the existing technology, the liquid cooling plate is placed on the panel manually, and then the withstand voltage tester is turned on to perform the insulation withstand voltage test. The operation is cumbersome and the testing efficiency is low. Utility Model Content

[0016] 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.
[0017] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0018] like Figure 1 As shown, this embodiment of the utility model includes a frame 4 that provides a worktable and a testing component 2, which is capable of performing insulation withstand voltage testing on the liquid cooling plate.
[0019] Specifically, the frame 4 is a frame structure with a horizontal surface, which is the mounting surface of the detection component 2. The liquid cooling plate is placed between the workbench and the detection component 2. After the detection component 2 comes into contact with the liquid cooling plate, it is powered on to perform insulation withstand voltage testing.
[0020] This embodiment includes two sets of detection components 2, which can simultaneously detect two sets of liquid cooling plates, thereby improving detection efficiency.
[0021] Furthermore, this embodiment also includes a conveying assembly 1 disposed on the frame 4, the conveying assembly 1 including a placement panel 13 for placing the liquid cooling plate, the placement panel 13 being able to convey the liquid cooling plate directly below the detection assembly 2; and a switch assembly 3 disposed on the frame 4, the switch assembly 3 being able to detect the position of the placement panel 13 relative to the detection assembly 2.
[0022] Specifically, the conveying assembly 1 is fixed to the horizontal surface of the frame 4 by bolts. The top surface of the placement panel 13 is equipped with a liquid cooling plate, which moves along the horizontal surface to convey the liquid cooling plate to the detection position of the detection assembly 2. This ensures that the height of the liquid cooling plate remains constant during the conveying process, thereby ensuring that the detection surface of the detection assembly 2 can fully fit with the surface of the liquid cooling plate to be detected, thus ensuring the accuracy of the detection.
[0023] Secondly, both the switch assembly 3 and the detection assembly 2 are fixedly connected to the frame 4, and their relative positions are always fixed. During the movement of the placement panel 13, the switch assembly 3 can limit its position relative to the frame 4, thereby limiting its position relative to the detection assembly 2, thus improving the positional accuracy of the liquid cooling plate relative to the detection assembly 2. Furthermore, the switch assembly 3 can control the conveying assembly 1 and the detection assembly 2, thereby realizing automatic feeding and automatic detection of the liquid cooling plate and improving detection efficiency.
[0024] Secondly, this embodiment includes two sets of placement panels 13 for placing liquid cooling plates, which work in conjunction with two sets of detection components 2 to improve detection efficiency.
[0025] Furthermore, a limiting block 14 is provided on the placement panel 13, which can limit the position of the liquid cooling plate relative to the placement panel 13.
[0026] Specifically, the top surface of the placement panel 13 is fixedly connected to a limiting block 14 by screws. The side of the limiting block 14 is used to limit the relative position between the liquid cooling plate and the placement panel 13. The limiting block 14 is connected between the two sets of placement panels 13, so that the limiting block 14 is formed with the middle position and the left position of the placement panel 13 as the reference position. The middle surface of the middle position of the placement panel 13 coincides with the middle surface of the middle position of the detection component 2. The left side of the placement panel 13 is limited by the switch component 3, thereby limiting the left position of the liquid cooling plate, thereby limiting the position of the liquid cooling plate and improving the positional accuracy of the liquid cooling plate relative to the detection component 2.
[0027] Furthermore, the conveying assembly 1 also includes: a movable slide rail 12 disposed on the frame 4; a movable cylinder 11 connected to the placement panel 13, the movable cylinder 11 being able to drive the placement panel 13 to move along the movable slide rail 12, and the liquid cooling plate placed on the placement panel 13 moving relative to the detection assembly 2; and a robot 15 fixedly placed relative to the frame 4, the moving end of the robot 15 being provided with a suction cup 16, the suction cup 16 being able to move the liquid cooling plate from a certain position to the placement panel 13.
[0028] Specifically, the movable slide rail 12 is fixed to the horizontal surface by screws, and the placement panel 13 is slidably connected to the movable slide rail 12, so that the movable cylinder 11 fixed on the left side of the movable slide rail 12 can push the placement panel 13 to move along the length direction of the movable slide rail 12, thereby pushing the liquid cooling plate to move relative to the detection component 2. The detection component 2 is fixed at the left end of the movable slide rail 12. The robot 15 places the liquid cooling plate on the placement panel 13 that has been moved to the right side by the suction cup 16. The movable cylinder 11 drives the placement panel 13 to move to the left until it reaches the limit position. The detection component 2 detects the liquid cooling plate, thereby realizing automatic feeding and automatic detection of the liquid cooling plate and improving detection efficiency.
[0029] The projection of the detection component 2 on the horizontal plane can cover the left end of the moving slide rail 12 but not its right end, so that the top of the placement panel 13, which moves to the moving slide rail 12, is unobstructed. This allows the suction cup 16 to place the liquid cooling plate on the placement panel 13 from above, achieving automatic feeding. The robot 15 can control the relative positional accuracy between the suction cup 16 and the placement panel 13, thereby improving the relative positional accuracy between the liquid cooling plate and the placement panel 13 during automatic feeding. Then, the switch component 3 controls the placement panel 13 to automatically move to the detection position of the detection component 2, achieving automatic detection and improving detection efficiency.
[0030] like Figure 2As shown, the switch assembly 3 includes: an infrared sensor 31 disposed on the rack 4, the infrared light of which can interfere with the suction cup 16 that places the liquid cooling plate on the placement panel 13; and a proximity switch 32 disposed on the rack 4, which can limit the position of the placement panel 13 relative to the detection assembly 2.
[0031] Specifically, the infrared sensor 31 is fixedly connected to the horizontal surface. Its working principle is that the transmitter actively emits modulated infrared light pulses, and the receiver detects the difference in the emitted infrared light pulses to determine the target state. In this embodiment, when the suction cup 16 places the liquid cooling plate on the placement panel 13, the suction cup 16 will block the infrared light pulses. When the suction cup 16 places the liquid cooling plate in place and leaves the placement panel 13, the receiver receives the undamaged infrared light pulses again, thereby determining whether the surface of the placement panel 13 is covered with a liquid cooling plate, and then controlling the moving cylinder 11 to move the placement panel 13 toward the detection component 2.
[0032] Secondly, the proximity switch 32 is fixedly connected to the horizontal plane. When the moving cylinder 11 moves the placement panel 13 to directly below the detection component 2, the right side of the placement panel 13 contacts the proximity switch 32, thereby controlling the moving cylinder 11 to stop moving the placement panel 13, thereby limiting the relative position of the liquid cooling plate and the detection component 2, thereby realizing the automation of the liquid cooling plate from feeding to detection and improving detection efficiency.
[0033] like Figure 3 As shown, the testing component 2 includes: a pressing cylinder 21 mounted on the frame 4, which is fixedly mounted on the frame 4 by a cylinder mounting component 22, which can adjust the position of the pressing cylinder 21 relative to the liquid cooling plate; a pressure plate 23 mounted on the moving end of the pressing cylinder 21, the side of the pressure plate 23 near the panel being connected to a conductive cotton 24 proximity switch, which can cause the pressing cylinder 21 to drive the conductive cotton 24 proximity switch to coincide with the insulation withstand voltage test area of the liquid cooling plate; and a withstand voltage tester 25, which can perform an insulation withstand voltage test on the liquid cooling plate.
[0034] Specifically, this embodiment includes two sets of detection components 2. The middle area of the cylinder mounting component 22 forms a through hole for fixing the pressing cylinder 21, and the two ends form waist holes. The position of the pressing cylinder 21 relative to the frame 4 is adjusted along the length direction of the waist holes, thereby adjusting its position relative to the liquid cooling plate. The movement direction of the pressing cylinder 21 is perpendicular to the horizontal plane, and thus perpendicular to the liquid cooling plate, so that the bottom surface of the pressure plate 23 is always horizontal during the movement, and thus the bottom surface of the conductive cotton 24 proximity switch is always horizontal during the movement, so that the conductive cotton 24 proximity switch can completely overlap and completely fit with the area of the liquid cooling plate that needs to be tested for insulation, thereby ensuring the accuracy of the withstand voltage tester 25 in performing insulation withstand voltage test on the liquid cooling plate.
