The acid corrosion of the terminal is caused by the incomplete sealing between the terminal and the terminal groove, which affects the sealing performance between the terminal and the terminal groove. The factor is the quality of the sealant used to seal the terminal groove and the terminal. Poor quality of the sealant will lead to poor bonding between the inner wall of the terminal groove and the outer wall of the terminal, making the seal between the two poor , Eventually lead to acid corrosion of the terminal; another reason that affects the sealing performance between the terminal and the terminal groove is due to the irregular operation of the staff, and the excessive screwing force during the charging process causes the sealant capillary phenomenon, and the sealant capillary phenomenon appears It will affect the sealing performance between the terminal and the terminal groove, resulting in defective products.

现有技术中,一旦端子出现爬酸腐蚀问题,则就会出现次品,次品率高则会严重提升生产成本,所以,迫切需要寻找一种工具或方法测试判定密封胶质量是否达标,同时能够找出端子爬酸腐蚀的真正原因并纠正,避免问题再次发生。In the prior art, once the terminal has the problem of creeping acid corrosion, defective products will appear, and the high defective rate will seriously increase the production cost. Therefore, it is urgent to find a tool or method to test whether the sealant quality meets the standard. It is possible to find out the real cause of the acid corrosion of the terminal and correct it to avoid the problem from happening again.

进一步地,在所述密封头的下表面还固定有橡胶嘴,所述气管的出气口延伸到所述橡胶嘴的下表面。由于橡胶材质具有受到压力径向展开的性能,在密封头下方设置橡胶嘴能够器的密封头与端子槽之间的间隙被密封的更好,提高本装置的检测可靠性。Further, a rubber nozzle is fixed on the lower surface of the sealing head, and the air outlet of the air pipe extends to the lower surface of the rubber nozzle. Since the rubber material has the performance of radial expansion under pressure, the gap between the sealing head and the terminal groove where the rubber nozzle is arranged under the sealing head is better sealed, which improves the detection reliability of the device.

本发明还提供了一种蓄电池极柱密封性能的检测方法,包括以下步骤:S1:将待测端子安装到中盖的端子槽内,并将所述待测端子的极柱与所述端子槽之间通过密封圈密封,然后 使用密封胶将待测端子的极柱和铜片与所述端子槽密封,形成整体结构,其中,有一部分所述铜片伸出到所述密封胶外部;S2:将所述整体结构倒置,即,将伸出到所述密封胶外部的所述铜片朝下、所述极柱朝上放置,向所述极柱与所述端子槽之间的间隙内注入检测液体;S3:将倒置的所述整体结构放在所述顶台上,拉动所述控制阀使所述气缸的伸缩杆上升至将所述端子槽的根部外沿与所述密封头的下表面锁紧密封;S4:手压所述压气泵,通过所述气管向所述密封头与所述端子槽之间的空间充气,至所述压力表的读数达到预设值后,关闭所述截止阀;S5:保压预设时间后,打开所述截止阀,取下所述整体机构,观察待测端子的铜片周围是否有所述检测液体渗漏,若有渗漏则能判定密封胶密封性能较差,否则密封胶密封效果较好。The present invention also provides a method for detecting the sealing performance of battery poles, which includes the following steps: S1: install the terminal to be tested into the terminal slot of the middle cover, and connect the pole of the terminal to be tested with the terminal slot Seal with a sealing ring, and then use sealant to seal the pole and copper sheet of the terminal to be tested with the terminal groove to form an integral structure, wherein a part of the copper sheet extends outside the sealant; S2 : Turn the overall structure upside down, that is, place the copper sheet protruding out of the sealant downwards and the poles upwards, into the gap between the poles and the terminal groove Inject the detection liquid; S3: Place the inverted overall structure on the top platform, pull the control valve to raise the telescopic rod of the cylinder to the outer edge of the root of the terminal groove and the sealing head The lower surface is locked and sealed; S4: Manually press the compressor to inflate the space between the sealing head and the terminal groove through the air pipe, and close the pressure gauge after the pressure gauge reaches the preset value. The cut-off valve; S5: After the pressure is maintained for a preset time, open the cut-off valve, remove the overall mechanism, and observe whether there is any leakage of the detection liquid around the copper sheet of the terminal to be tested. If there is leakage, it can be determined The sealing performance of the sealant is poor, otherwise the sealing effect of the sealant is better.

优选地,在所述S4中,所述预设值小于所述气缸的顶压力,且所述预设值为15-40kpa。从上端施加到密封头与端子槽之间的压力要小于气缸的顶压力,以保证测试结果的准确性。Preferably, in the S4, the preset value is less than the top pressure of the cylinder, and the preset value is 15-40 kpa. The pressure applied from the upper end between the sealing head and the terminal groove should be less than the top pressure of the cylinder to ensure the accuracy of the test results.

优选地,在所述S3中,在将所述整体结构倒置放在所述顶台上之前,还在所述顶台上平铺显色纸。若密封胶质量较差,在上方压力的作用下,检测液体会从端子槽与密封头之间的空间向下经端子槽内壁与密封胶之间和/或密封胶与端子外壁之间向下渗漏,直至检测液体沿端子外壁渗漏到下方的显色纸上,这样,只要显色纸上有检测液体出现就能够判断端子与端子槽之间密封不良,也就能判断密封胶质量较差了,判断简单方便。Preferably, in the S3, before placing the overall structure upside down on the top table, the coloring paper is also laid flat on the top table. If the quality of the sealant is poor, under the action of the upper pressure, the detection liquid will go down from the space between the terminal slot and the sealing head, through the inner wall of the terminal slot and the sealant and/or between the sealant and the outer wall of the terminal. Leakage until the detection liquid leaks along the outer wall of the terminal to the color paper below.

有益效果:本装置在检测端子与端子槽之间的密封性能时,只需将使用密封胶将端子与端子槽密封成整体结构,接着将整体结构倒置,并端子槽与端子的极柱之间的间隙内注入检测液体,然后将倒置的整体结构放在顶台上,通过气缸将顶台上移至整体结构的端子槽根部外沿与密封头锁紧密封,然后通过压气泵向密封头与端子槽之间的空间内充气施压,该空间内的压力达到一定值后,若端子与端子槽之间的密封胶的密封良好,则上述空间内的压力不会将检测液体压入极柱外壁与密封胶之间的间隙,即检测液体不会从端子下部的铜片外壁与密封胶之间的间隙泄漏出去;反之,若端子与端子槽之间的密封胶的密封不好,则上述空间内的压力会将检测液体压入极柱外壁与密封胶之间的间隙,即检测液体会从端子下部的铜片外壁与密封胶之间的间隙泄漏出去;检测液体是否有泄漏通过肉眼观察就能获取。Beneficial effects: When the device detects the sealing performance between the terminal and the terminal groove, only the terminal and the terminal groove are sealed into an integral structure with a sealant, and then the overall structure is inverted, and the terminal groove and the pole post of the terminal Inject the test liquid into the gap between the two, and then place the inverted overall structure on the top platform, move the top platform to the terminal groove root outer edge of the overall structure and seal the sealing head through the cylinder, and then use the air compressor to seal the sealing head and The space between the terminal grooves is inflated and pressurized. After the pressure in the space reaches a certain value, if the sealant between the terminal and the terminal groove is well sealed, the pressure in the above space will not press the detection liquid into the pole The gap between the outer wall and the sealant, that is, the detection liquid will not leak from the gap between the outer wall of the copper sheet at the bottom of the terminal and the sealant; on the contrary, if the sealant between the terminal and the terminal groove is not properly sealed, the above The pressure in the space will press the detection liquid into the gap between the outer wall of the pole and the sealant, that is, the detection liquid will leak out from the gap between the outer wall of the copper sheet at the bottom of the terminal and the sealant; check whether the liquid has leaked by naked eyes Can get it.

可见,本装置结构简单,检测快捷方便,能够检测密封胶的密封性;同时,通过以上 检测方法,还可以模拟端子内部爬酸轨迹,查找爬酸的真正原因,为提升产品质量提供有效保证。It can be seen that the device has a simple structure, quick and convenient detection, and can detect the tightness of the sealant; at the same time, through the above detection methods, it can also simulate the internal creeping trajectory of the terminal to find the true cause of the creeping, and provide an effective guarantee for improving product quality.
