Description

Technical Field

[0001] The utility model relates to the field of liquid cooling plate quality inspection equipment, in particular to a large liquid cooling plate sealing detection system. Background Art

[0002] New energy vehicle batteries are new types of automotive batteries that use new energy technologies to reduce greenhouse gas emissions. They can be divided into two categories, namely batteries and fuel cells. Batteries are suitable for pure new energy vehicles and can be classified as lead-acid batteries and nickel-based batteries. Liquid cooling plates can reduce the excess heat generated by battery operation in power battery systems. The heat is transferred through the battery or module and the surface of the liquid cooling plate in contact, and is eventually carried away by the coolant passing through the internal flow channel of the liquid cooling plate. During the production process, the liquid cooling plate needs to be tested for sealing.

[0003] Existing liquid cooling plates used in new energy vehicle batteries are relatively large in size because most battery packs of new energy vehicles are composed of multiple batteries stacked in series. During the process of performing sealing leak detection operations on such battery panels, due to the volume limitation of the liquid cooling plates, only one liquid cooling plate can be tested for sealing at one workstation, resulting in slow operation speed and low detection efficiency.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-4 A large liquid cooling plate sealing detection system shown includes a leak detection mechanism 1 and lifting mechanisms 2 arranged on both sides of the leak detection mechanism 1, and a conveying mechanism 3 capable of transferring the liquid cooling plate is arranged on one side of the lifting mechanism 2 away from the leak detection mechanism 1.

[0024] The leak detection mechanism 1 includes a frame, and no less than two vacuum boxes 11 are arranged inside the frame from top to bottom. The arrangement of multiple vacuum boxes 11 can save the space occupied by the vacuum boxes 11, and can perform helium leak detection operations on multiple liquid cooling plates under a vacuum state. It is suitable for the leak detection environment of large liquid cooling plates and improves the efficiency of helium leak detection operations. A conveying chain group 13 that can transfer liquid cooling plates is arranged in the vacuum box 11. Both sides of the vacuum box 11 facing the lifting mechanism 2 are arranged with lifting and lowering sealing baffles 12. The frame is provided with a driving cylinder 14 that can control the lifting and lowering movement of the sealing baffle 12. When the sealing baffle 12 rises to the limit position, the openings on both sides of the vacuum box 11 are opened to accommodate the large liquid cooling plate. When the sealing baffle 12 drops to the limit position, the sealed state inside the vacuum box 11 can be maintained.

[0025] The lifting mechanism 2 includes a material transfer seat 21, on which a second conveying chain group 22 is arranged that can transfer the liquid cooling plate to the inside of the vacuum box 11, and the material transfer seat 21 is connected to a lifting device 23 that can transfer it to different heights. When the material transfer seat 21 is transferred to different heights, it can correspond to vacuum boxes 11 at different heights. The second conveying chain group 22 can move the liquid cooling plate on the surface of the material transfer seat 21 into the inside of the vacuum box 11.

[0026] Through the lifting mechanism 2, the large liquid cooling plate can be quickly and stably moved into the vacuum box 11, which is adapted to vacuum boxes 11 of different heights, reducing errors in manual material transfer operations, ensuring stability and accuracy during the material transfer process, and improving the efficiency of transferring the liquid cooling plate.

[0027] like Figure 4 , Figure 5 As shown, the conveying mechanism 3 includes a lifting platform 31 and a conveying platform 32. The lifting platforms 31 located on both sides of the leak detection mechanism 1 are responsible for the loading and unloading operations of the liquid cooling plate. After the liquid cooling plate is placed on the lifting platform 31, the lifting platform 31 can drive the liquid cooling plate to rise. When the lifting platform 31 rises to the maximum height, it is flush with the conveying platform 32, and the liquid cooling plate is transferred to the conveying platform 32. Subsequently, the conveying platform 32 can convey the liquid cooling plate to the material transfer seat 21 or receive the liquid cooling plate unloaded by the material transfer seat 21, and the material transfer seat 21 transfers the liquid cooling plate to the inside of the vacuum box 11, and performs a helium leak detection operation under a vacuum state on the liquid cooling plate.

[0028] like Figure 2 As shown, the surface of the vacuum box 11 is provided with a plurality of interfaces 111. In order to perform vacuuming and helium filling operations in the vacuum box 11, a vacuuming device 4 and a helium pumping device 5 are provided on the outside of the frame, and the vacuuming device 4 and the helium pumping device 5 are both connected to the interfaces 111.

[0029] like Figure 2 As shown, in order to recycle the helium, a helium recovery device 7 is provided on the outside of the frame. The helium recovery device 7 is connected to the helium extraction device 5, and the helium inside the vacuum box 11 can be recovered into the helium recovery device 7. The helium recovery device 7 can reintroduce the helium into the helium extraction device 5 to realize the recycling of the helium.

[0030] like Figure 2 As shown, a helium detection device 6 is provided on the outside of the rack, and the helium detection device 6 is connected to the vacuum box 11. The helium detection device 6 includes a sensor that can sense the helium leakage state inside the vacuum box 11 and a numerical control device that is communicatively connected to the sensor. If the liquid cooling plate in the vacuum box 11 has a leak, the sensor can sense it in real time, detect the concentration of the leaked helium, and transmit the data to the numerical control device, which performs data analysis and processing and outputs the judgment result to the terminal PLC controller.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
