Description

Technical Field

[0001] The utility model relates to the technical field of airtightness detection, in particular to an airtightness detection device for battery terminal posts. Background Art

[0002] A battery terminal post refers to the connection post of the positive and negative electrodes of a battery. Its diameter is relatively slender, and sometimes a special battery connector is required for connection. A terminal is not related to the battery and is a fixing device for connecting wires or other devices, usually made of metal. Battery terminal posts are usually cylindrical, with different lengths and diameters, so corresponding-sized connectors are needed for connection. The shapes of terminals are diverse, including cylindrical, drop-shaped, U-shaped, etc., but they all have the function of fixing wiring.

[0003] Publication No. (CN220472893U) discloses an airtightness detection device for battery terminal posts. When starting the detection, the device is placed in a water bath, and the valve is opened to introduce compressed air into the compressed air pipe. Subsequently, it is observed whether there are bubbles escaping from the surface of the battery terminal post and whether the pointer of the pressure gauge changes within 30s. If the pointer of the pressure gauge does not change and there are no bubbles escaping from the surface of the battery terminal post, it is determined that the airtightness of the battery terminal post is qualified; otherwise, it is unqualified. After the detection is completed, the device is taken out of the water bath, the bolt is turned upward and then the crossbar is rotated to deviate it from above the battery terminal post, and then the battery terminal post can be taken out. After the battery terminal post is installed, the device needs to be placed in the water bath to conduct the detection. During the process of moving the device, the crossbar may be touched, which will affect the sealing effect of the device and the detection result, and improvement is needed.

[0026] As Figures 1-5 shown, a battery terminal airtightness detection device includes a moving mechanism 1, and further includes a detection mechanism 2 for detecting the airtightness of the battery terminal. The detection mechanism 2 is fixed above the moving mechanism 1.

[0027] In the present utility model, the moving mechanism 1 includes a moving plate 101 and moving wheels 102. The moving wheels 102 are installed below the moving plate 101. The thickness of the moving plate 101 is 2.5 centimeters. The moving wheels 102 are rotatably connected to the moving plate 101. The arrangement of the moving wheels 102 makes the movement of the device more convenient.

[0028] In the present utility model, the detection mechanism 2 includes a support rod 201, a water tank 202, a first fixing bracket 203, an electric push rod 204, a push plate 205, a fixing shell 206, a fixing plate 207, a detection cylinder 208, a sealing gasket 209, an air inlet pipe 210, a first valve 211, a second fixing bracket 212, a cylinder 213, a lifting plate 214, and a pressing rod 215. The water tank 202 is fixed above the support rod 201. The first fixing bracket 203 is installed on the water tank 202. The electric push rod 204 is installed on the first fixing bracket 203. The push plate 205 is fixed above the electric push rod 204. The fixing shell 206 is installed above the water tank 202. The fixing plate 207 is installed inside the fixing shell 206. The detection cylinder 208 is fixed above the fixing plate 207. The sealing gasket 209 is fixed inside the detection cylinder 208. The air inlet pipe 210 is fixed at the front of the detection cylinder 208. The first valve 211 is fixed on the air inlet pipe 210. The second fixing bracket 212 is installed above the fixing shell 206. The cylinder 213 is installed above the second fixing bracket 212. The lifting plate 214 is fixed at the telescopic end of the cylinder 213. The pressing rod 215 is fixed below the lifting plate 214. The sealing gasket 209 is bonded to the detection cylinder 208, and the material of the sealing gasket 209 is rubber. When using the device, place the battery terminal to be detected on the detection cylinder 208, start the cylinder 213, the operation of the cylinder 213 drives the lifting plate 214 and the pressing rod 215 to descend, and the descent of the pressing rod 215 squeezes and fixes the battery terminal. Then start the electric push rod 204, the elongation of the electric push rod 204 drives the push plate 205 to rise, and the rising of the push plate 205 pushes the water in the water tank 202 into the fixing shell 206. When the battery terminal is completely immersed in water, control the electric push rod 204 to stop running, open the first valve 211, and compressed air enters the inside of the detection cylinder 208 through the air inlet pipe 210. If the airtightness of the battery terminal is poor, the compressed air in the detection cylinder 208 will pass through the battery terminal and enter the water to form bubbles. If the airtightness of the battery terminal is good, the compressed air in the detection cylinder 208 cannot pass through the battery terminal, and no bubbles will be generated in the water. The airtightness of the battery terminal is detected in the above manner, and the fixed battery terminal does not need to be moved, so as to ensure that the detection result is not affected.

[0029] In the present utility model, a collection mechanism 3 is installed on the detection mechanism 2. The collection mechanism 3 includes a collection box 301, a water delivery pipe 302, and a second valve 303. The water delivery pipe 302 is fixed on both sides of the collection box 301, and the second valve 303 is fixed on the water delivery pipe 302. The water delivery pipe 302 is welded to the collection box 301, and the material of the water delivery pipe 302 is stainless steel. When the push plate 205 rises to a relatively high height due to improper operation, water will overflow from the fixed shell 206, and the overflowed water will fall into the collection box 301. After the detection is completed, the push plate 205 is controlled to return to its original position, and then the second valve 303 is opened. The water in the collection box 301 returns to the water tank 202 through the water delivery pipe 302. By adopting the above method, the overflowed water can return to the water tank 202, effectively saving water resources.

[0030] In the above structure: When using the device, the battery terminal to be detected is placed on the detection cylinder 208, the cylinder 213 is started, the operation of the cylinder 213 drives the lifting plate 214 and the pressure rod 215 to descend, and the pressure rod 215 descends to squeeze and fix the battery terminal. Then, the electric push rod 204 is started, and the electric push rod 204 extends to drive the push plate 205 to rise. The push plate 205 rises to push the water in the water tank 202 into the fixed shell 206. When the battery terminal is completely immersed in water, the electric push rod 204 is controlled to stop operating. When the push plate 205 rises to a relatively high height due to improper operation, water will overflow from the fixed shell 206, and the overflowed water will fall into the collection box 301. The first valve 211 is opened, and compressed air enters the interior of the detection cylinder 208 through the air inlet pipe 210. If the airtightness of the battery terminal is poor, the compressed air in the detection cylinder 208 will pass through the battery terminal and enter the water to form bubbles. If the airtightness of the battery terminal is good, the compressed air in the detection cylinder 208 cannot pass through the battery terminal, and no bubbles will be generated in the water. After the detection is completed, the push plate 205 is controlled to return to its original position, then the second valve 303 is opened, the water in the collection box 301 returns to the water tank 202 through the water delivery pipe 302, and then the pressure rod 215 is controlled to return to its original position. Subsequently, the battery terminal can be taken.
