Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic scanning detection technology, and specifically relates to an ultrasonic scanning waterproof carrier. Background Technology

[0002] With the continuous development of electric vehicles, the demand for lithium batteries is increasing. During the production process, the top terminals and the top cover of the battery need to be welded together. Since welding involves joining the cylindrical gaskets and welding pieces of each terminal, defects can occur, leading to quality problems in the lithium battery. Common welding defects include incomplete welding, burn-through, weak welds, thin weld seams, and cracks. Therefore, defect detection of lithium battery terminal welding is necessary.

[0003] Currently, industrial production lines still rely primarily on visual inspection by workers. Due to the uncertainty of manual sampling and factors such as physical fatigue, quality problems still arise. Ultrasonic scanning technology can detect metal weld points on battery casings and is increasingly used in the inspection of battery casing welds. However, since ultrasonic scanning requires the scanning surface to contact the ultrasonic probe through a water medium, water ingress into the battery casing can severely affect the safety of subsequent product use. Therefore, waterproof carriers are needed for scanning and inspecting battery casings to allow the ultrasonic probe to detect weld defects.

[0004] In the prior art, the inventors have found that waterproof carriers have at least the following technical problems: conventional waterproof carriers seal the entire battery casing inside and place the waterproof carrier in water. When the weld seams of the battery casing are scanned and detected by an ultrasonic probe, the parts other than the weld seam area of ​​the battery casing are easily wetted by water, and water may even enter due to the poor sealing of the battery casing, thereby affecting the performance of the battery.

[0005] Therefore, it is necessary to improve upon the shortcomings of existing technologies in order to overcome their deficiencies in practical applications. Utility Model Content

[0006] Based on the aforementioned shortcomings and deficiencies in the prior art, one of the objectives of this utility model is to at least solve one or more of the aforementioned problems in the prior art.

The sealing cover 2 is provided with a water tank 21. The bottom end of the water tank 21 is arranged opposite the terminal post 61 of the battery case 6 and is tightly fitted with the terminal post through a sealing element.

[0033] In some embodiments of this application, the top plate mechanism 3 includes a top plate 31, a bolt 32, a spring 33, and a second handle 34. The bolt 32 is rotatably engaged with the back side wall 12 of the housing 1 and connected to the top plate 31. The spring 33 is installed between the top plate 31 and the back side wall 12 of the housing 1, and the bolt 32 is connected to the second handle 34.

[0034] Specifically, bolts 32 are mounted on the top plate 31, and a spring 33 is provided between the back side wall 12 of the box 1 and the top plate 31 and is fitted onto the bolts 32. A second handle 34 is provided on the outside of the back side wall 12 and fixed onto the bolts 32. By rotating the second handle 34, the position of the top plate 31 inside the box 1 can be adjusted. At this time, the spring 33 is compressed, and the top plate 31 can be fixed.

[0035] In some embodiments of this application, two optical axes 51 are installed between the front sidewall 11 and the back sidewall 12 of the housing 1, and two linear bearings 52 are respectively installed on the top plate 31 and the pressure plate 41. Each optical axis 51 is connected to the corresponding two linear bearings 52, and the linear bearings 52 can move along the optical axis 51.

[0036] Furthermore, an elastic element 53 is installed between the pressing plate 41 and the front side wall 11 of the housing 1. The elastic element 53 is sleeved on the optical axis 51 and is used to adjust the distance between the pressing plate 41 and the front side wall 11 of the housing 1.

[0037] In some embodiments of this application, the locking mechanism 4 includes a pressing plate 41, a rotating shaft 42, a guide shaft 43, a fixing plate 44, and a first handle 45. The guide shaft 43 is installed between the fixing plate 44 and the pressing plate 41. The rotating shaft 42 and the first handle 45 are installed on the fixing plate 44, and the first handle 45 is connected to the rotating shaft 42. One end of the rotating shaft 42 is rotatably engaged with the front side wall 11 of the housing 1, and the other end of the rotating shaft 42 is rotatably engaged with the fixing plate 44.

[0038] Specifically, two guide shafts 43 are installed between the clamping plate 41 and the fixing plate 44. The outer side of the fixing plate 44 is connected to the first handle 45. The inner side of the fixing plate 44 is provided with a rotating shaft 42. The end of the rotating shaft 42 is provided with a positioning pin 421. The position of the positioning pin 421 can be changed by rotating the first handle 45. Two elastic elements 53 are respectively installed on the optical shafts 51 on both sides and respectively abut against the clamping plate 41 and the front side wall 11 of the housing 1. By pulling the first handle 45, the position of the clamping plate 41 can be adjusted at will. Releasing the first handle 45 can return the clamping plate 41 to the initial position. Releasing the first handle 45 adjusts the positioning pin 421 to the vertical direction, so that the positioning pin 421 is locked on the outer side of the front side wall 11 of the housing, and the clamping plate 41 can be fixed in a position away from the top plate 31. When the first handle 45 is rotated to adjust the positioning pin 421 to the horizontal direction, the positioning pin 421 moves along the flat groove 111, and the clamping plate 41 will move to a position close to the top plate 31.

[0039] Depending on the thickness of different types of battery casings, the position of the pressing plate 41 can be adjusted by rotating the first handle 41, and the position of the top plate 31 can be adjusted by rotating the second handle 34, thus adapting to battery casings 6 of different thicknesses.

[0040] In some embodiments of this application, the sealing cover 2 is provided with two water tanks 21, and the bottom end of the water tank 21 is provided with an opening groove 211.

By adjusting the position of the water tanks 21 through the waist hole, the spacing between the two water tanks can be adjusted according to the position between the two terminals of the battery case, thereby adapting to different types of battery cases.

[0042] In some embodiments of this application, the rear end of the sealing cover 2 is rotatably connected to the housing 1, and a latch 13 is installed between the front end of the sealing cover 2 and the housing 1 to facilitate the insertion or removal of the battery case from the housing.

[0043] According to some embodiments of this application, an ultrasonic scanning waterproof carrier is used as follows: The second handle 34 is rotated according to the thickness of the battery casing 6 to adjust the position of the top plate 31. The second handle 34 is pulled outwards, and the battery casing 6 is placed inside the housing 1, so that the back sidewall of the battery casing 6 abuts against the top plate 31. The first handle 45 is rotated to adjust the position of the clamping plate 41, so that the stepped surface of the clamping plate 41 abuts against the front sidewall of the battery casing 6. Based on the position of the terminal post 61 of the battery casing 6 in this state, the two water tanks 21 on the sealing cover 2 are adjusted so that the lower opening slot 211 of the water tank 21 can engage with the terminal post 61 of the battery casing. The sealing cover 2 is closed to the housing 1 by the latch 13. At this time, the sealing ring 13 is in close contact with the terminal post 61 of the battery casing without gaps. The terminal post 61 of the battery casing is exposed through the opening slot 211 of the water tank 21, directly contacting the water medium in the water tank. An ultrasonic probe is immersed in the water tank 21 to scan the surface of the terminal post of the battery casing.
