Technical Field
[0001] The present invention relates to the technical field of battery liquid cooling plate detection, in particular to a detection device and a detection method for a battery liquid cooling plate. Background Art
[0002] Battery liquid cooling plates play an important role in the field of new energy. They are mainly used in the heat dissipation system of batteries to ensure that the heat generated by the batteries during operation can be dissipated promptly and effectively, thereby maintaining the stability of the batteries and extending their service life. The liquid cooling plate quickly removes the heat generated by the batteries through the circulation of coolant inside it, and releases the heat to the external environment through the radiator. This heat dissipation method is more efficient than the traditional air cooling method, especially under high load and long-term operation. The advantages of liquid cooling plates are more obvious. The production process of battery liquid cooling plates must undergo full-size inspection and flatness inspection; The battery liquid cooling plate testing equipment on the market mainly tests the sealing, flatness and overall size of the liquid cooling plate, and often uses technologies such as air tightness test, laser plane detection and visual size detection. These devices can meet the liquid cooling plate detection needs to a certain extent, but during the detection process, the positioning and support effect of the liquid cooling plate has an important influence on the detection accuracy, especially when testing liquid cooling plates of different specifications, the flexibility and stability of the support and positioning device become the key factors that determine the reliability of the detection results; The liquid cooling plate detection equipment in the prior art usually relies on a single form of support structure or fixing method to position and detect the liquid cooling plate. However, after the liquid cooling plate is placed on the bracket and turned over, the edge of the battery liquid cooling plate will warp. When faced with shape differences or slight warping of some liquid cooling plates, some liquid cooling plate detection equipment in the prior art cannot fully adapt, thereby affecting the matching accuracy between the liquid cooling plate and the detection equipment. In this case, the detection results will be affected by unstable support or inaccurate positioning of the liquid cooling plate.

[0023] Please refer to the attached Figure 8 The fixing mechanism 9 includes a pull rod 902, which is slidably connected to the inside of the mounting block 16. A clamping block 903 is fixed to the side of the pull rod 902 close to the laser ranging sensor 15. The pull rod 902 is connected to the clamping block 903, and the pull rod 902 can slide in the mounting block 16.

The limit plate 1001 is connected to the pull rod 902. When the pull rod 902 moves, the limit plate 1001 can be driven to move together. The compression spring 1002 will be squeezed and compressed by the limit plate 1001 when the limit plate 1001 moves. After the compression spring 1002 loses the squeezing of the limit plate 1001, the compression spring 1002 generates a reset movement, thereby pushing the limit plate 1001 to move, and then the limit plate 1001 controls the movement of the pull rod 902 to achieve convenient operation.
[0027] The present invention also provides a method for detecting a battery liquid cooling plate, comprising the following steps: S1. When testing the battery liquid cooling plate, place the battery liquid cooling plate on top of the bracket 2, and then use the screw moving frame 11 to drive the battery liquid cooling plate to move toward the flattening frame 3; S2. The pressure of the connecting rod 502 is monitored in real time by the pressure sensor 17. When the pressure exceeds the preset value, the detection work can be stopped and the battery liquid cooling plate is returned; S3. When the pressure does not exceed the preset value, the warped edge of the battery liquid cooling plate is fine-tuned and flattened by moving the pressing plate 709 downward to further improve the detection accuracy; S4, flexibly adjusting the position of the laser distance sensor 15 through the lateral moving frame 12 and the longitudinal moving frame 13, so that the laser distance sensor 15 performs flatness detection on the battery liquid cooling plate; S5. After the flatness detection is completed, the laser distance sensor 15 is replaced with a high-definition camera to perform a full-size detection on the battery liquid cooling plate.
[0028] Working principle: when testing the battery liquid cooling plate, the battery liquid cooling plate is placed on the top of the bracket 2, and multiple rubber sleeves 503 and positioning pins 505 are in contact with the battery liquid cooling plate, and then the bracket 2 drives the battery liquid cooling plate to move toward the flattening frame 3 through the screw moving frame 11, so that the metal sleeve 4 at the bottom of the flattening frame 3 is plugged into the metal sleeve 4 at the top of the bracket 2. After the bracket 2 contacts the flattening frame 3, the connecting rod 502 slides along the spring 601 and squeezes the sliding rod 602. After the sliding rod 602 is squeezed, a force can be applied to the connecting rod 502 to make the connecting rod 502 always in contact with the flattening frame 3. When the connecting rod 502 contacts the flattening frame 3, the pressure sensor 17 will monitor the pressure of the connecting rod 502 in real time. When the pressure exceeds the preset value of the connecting rod 502, the detection work can be stopped and the battery liquid cooling plate can be sent back. When the pressure does not exceed the preset value of the connecting rod 502, the detection work can continue. Then, the electric push rod 702 is started, and the telescopic end of the electric push rod 702 extends out to move the connecting frame 703 away from the flattening frame 3. When the connecting frame 703 moves, the transmission rod 704 will drive the right-angled trapezoidal block 1 705 to move together. When the right-angled trapezoidal block 1 705 moves, the isosceles trapezoidal block 801 on the top of the right-angled trapezoidal block 1 705 will slide in the isosceles trapezoidal groove 802 opened inside the right-angled trapezoidal block 2 706, thereby applying a force to the right-angled trapezoidal block 2 706 to make the right-angled trapezoidal block 2 706 move vertically. When the right-angled trapezoidal block 2 706 moves vertically, the slider 707 on one side of the right-angled trapezoidal block 2 706 will slide in the protective shell 701. When the right-angled trapezoidal block 2 706 moves downward, the connecting rod 708 will drive the flattening plate 709 to move further downward, thereby fine-tuning and flattening the warped edge of the battery liquid cooling plate, further improving the detection accuracy. After the battery liquid cooling plate is flattened, the position of the laser distance sensor 15 can be flexibly adjusted through the horizontal moving frame 12 and the vertical moving frame 13, so that the laser distance sensor 15 can perform flatness detection on the battery liquid cooling plate. After the flatness detection is completed, the laser distance sensor 15 is replaced with a high-definition camera to perform full-size detection on the battery liquid cooling plate. By pulling the pull ring 901, the pull ring 901 drives the pull rod 902 to move together. During the movement of the pull rod 902, the limit plate 1001 will move to squeeze the compression spring 1002, and the pull rod 902 will drive the block 903 to move. 03 After sliding out from the laser ranging sensor 15, the laser ranging sensor 15 can be removed, and then the dedicated ultra-clear camera is placed in the middle of the embedded mounting block 16, and then the pull ring 901 is loosened. After loosening the pull ring 901, the compression spring 1002 loses the squeezing of the limit plate 1001, thereby generating a reset movement. When the compression spring 1002 generates a reset movement, the compression spring 1002 will push the limit plate 1001 to move, so that the limit plate 1001 drives the pull rod 902 to move, so that the pull rod 902 controls the block 903 to move, and the block 903 slides into the camera housing to complete the installation, and then a full-size inspection is performed.
