Description

Technical Field

[0001] The invention relates to the field of battery processing equipment, and in particular to an automatic OCV testing device for a battery. Background Art

[0002] In the battery production process, the finished battery needs to go through the last inspection process to detect whether the battery's voltage, current, resistance and other parameters are within the qualified range before it can be packaged and sold. When measuring the battery parameters, the probe on the measuring equipment is connected to the positive and negative ears of the battery respectively, and then the battery is powered on for inspection. However, during the inspection process, some unqualified batteries will short-circuit after power is turned on, and even cause the battery to catch fire. The current inspection equipment is not equipped with a fire extinguishing mechanism to deal with battery fires. The burning battery can only be manually moved out of the equipment and then extinguished. Not only is the fire extinguishing efficiency low, but it also poses a threat to the safety of the operator. Therefore, it is necessary to produce a battery automatic OCV testing equipment that can safely and quickly extinguish the burning battery to solve the above problems. Summary of the invention

[0055] The battery fire extinguishing mechanism 7 of the present design is installed on the battery detection equipment for supporting use. The water tank 71 contains liquid for fire extinguishing. The water tank 71 is pushed under the cover assembly 72 along the guide assembly 73, and then the water tank 71 is fixed by the positioning assembly 74. When the battery on the battery detection equipment catches fire, the Y-axis drive assembly 721 immediately drives the movable cover 725 to open, and the manipulator on the battery detection equipment can place the burning battery or the entire material frame containing the battery into the water tank 71. After the Y-axis drive assembly 721 drives the movable cover 725 to reset, the third Z-axis cylinder 724 drives the movable cover 725 to move downward and block the opening of the water tank 71, so that oxygen cannot enter the water tank 71. In the state of isolating oxygen and under the action of the liquid in the water tank 71, the burning battery can be safely and quickly extinguished, and the detection equipment can still operate normally, avoiding shutdown operations and improving production efficiency.

[0056] The water tank 71 is provided with four sets of universal wheels 711 at the bottom thereof, and the four sets of universal wheels 711 correspond to the four corners of the bottom of the water tank 71 , so as to facilitate the movement of the water tank 71 .

[0057] The guide assembly 73 includes a guide mounting plate 731 and a guide wheel 732. The guide mounting plate 731 is fixedly arranged on both sides of the water tank 71. The guide wheels 732 are arranged in multiple groups and are rotatably mounted on the guide mounting plate 731. The guide wheels 732 correspond to the outer wall of the water tank 71. When the water tank 71 is pushed under the cover assembly 72, the outer walls on both sides of the water tank 71 contact with the guide wheels 732, and under the guiding action of the guide wheels 732, the water tank 71 is placed under the cover assembly 72 in an accurate position.

When the water tank 71 is pushed under the cover assembly 72, the first sensor 745 senses the water tank 71, while the second sensor 746 does not sense the water tank 71, which means that the water tank 71 is parked in the correct position. At this time, the third Y-axis cylinder 742 drives the positioning block 744 to slide in the guide block 743. The positioning block 744 approaches the water tank 71 and corresponds to the outer wall on one side of the water tank 71. The outer wall on the other side of the water tank 71 contacts the frame 1 on the equipment, thereby fixing the water tank 71 between the frame 1 and the positioning block 744.
