[0002] Lead-acid batteries are batteries whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. In the traditional production process, formation is a key step in pre-charging the battery to activate the active materials. Traditional formation is carried out in a normal environment, and the gas generated inside the cell is difficult to expel, which affects the formation of the SEI film. In order to avoid this phenomenon, it is usually carried out in a vacuum environment, thus forming the vacuum formation process.
[0003] Existing vacuum formation devices for acid batteries precharge the batteries through a charging chamber during use. Multiple batteries are charged in a vacuum state, which causes a large amount of heat to accumulate in the charging chamber, resulting in a sharp rise in internal temperature. In severe cases, this can damage the batteries and poses certain safety hazards. Utility Model Content

The cooling chamber 6 is fixedly connected to the charging chamber 2 and contains a certain amount of coolant. Two cooling water tanks 9 are fixedly connected to the outer surface of the formation cabinet 1 and also contain a certain amount of coolant. One of the cooling water tanks 9 is connected to the cooling chamber 6 via an inlet pipe 7. The inlet pipe 7 is equipped with a one-way valve to ensure that coolant can only enter through the inlet pipe 7. An outer cooling water tank 9 is connected to the cooling chamber 6 via an outlet pipe 8. A one-way valve is installed in the outlet pipe 8 to ensure that the coolant can only be discharged from the outlet pipe 8. The two cooling water tanks 9 are connected via a connecting pipe 10. A piston plate 11 is slidably connected inside the cooling water tank 9. The piston plate 11 and the cooling water tank 9 are sealed. The two piston plates 11 are fixed together by a connecting rod 12. The connecting rod 12 and the cooling water tank 9 are leak-proof. A sealing gasket is provided at the interface. The connecting rod 12 and the cooling water tank 9 are slidably connected.
[0028] A rotating shaft 13 is rotatably connected to the formation cabinet 1. An eccentric wheel 14 is fixedly connected to the outer surface of the rotating shaft 13. A moving plate 15 is fixedly connected to the outer surface of the connecting rod 12. The moving plate 15 is slidably connected to the eccentric wheel 14 and the formation cabinet 1. A cam is provided on the outer surface of one end of the rotating shaft 13. A push plate 16 is slidably connected to the inner wall of the formation cabinet 1. A limit block is provided on the outer surface of the push plate 16. A limit groove is opened on the inner wall of the formation cabinet 1. The limit block is slidably connected in the limit groove, thereby limiting the push plate 16. The cam is slidably connected to the push plate 16. An absorption chamber 21 is fixedly connected to the inner wall of the formation cabinet 1. A return spring is provided between the push plate 16 and the outer surface of the absorption chamber 21. A rack plate 17 is fixedly connected to the outer surface of the push plate 16. When the return spring is activated, the rack plate 17 can return to its original position. A straight rod is provided inside the formation cabinet 1. A spur gear 18 is fixedly connected to the outer surface of the straight rod. A stirring rod is rotatably connected inside the absorption chamber 21. A stirring rod 20 is connected to a spur gear 18 that meshes with a rack plate 17. A bevel gear 19 is fixedly connected to one end of the stirring rod 20 that passes through the absorption chamber 21. The bevel gear 19 meshes with the spur gear 18. A placement plate 22 is slidably connected inside the absorption chamber 21. A certain amount of dry absorbent is placed on the placement plate 22 for absorbing acid mist. A pressure spring is provided between the placement plate 22 and the inner wall of the absorption chamber 21. An indicator rod is provided on the placement plate 22 with a scale. Two slide rails 23 are fixedly connected to the inner wall of the formation cabinet 1. A slide rod is provided inside the slide rail 23. A slider 24 is slidably connected to the outer surface of the slide rod. The slider 24 is fixedly connected to the charging chamber 2. A telescopic cylinder is provided inside the formation cabinet 1. The telescopic cylinder is existing technology and can drive the lifting plate 4 to move up and down. The telescopic cylinder is fixedly connected to the lifting plate 4. Multiple partitions 5 are fixedly connected inside the charging chamber 2. The partitions 5 are interconnected to form multiple spaces. A cooling chamber 6 surrounds the entire partition 5.
[0029] In this invention, when lead-acid batteries need to undergo formation treatment, multiple batteries are placed into spaces separated by multiple partitions 5. A telescopic cylinder is activated, causing the lifting plate 4 to move. The lifting plate 4 moves to the charging compartment 2, and an external servo motor drives the rotating shaft 13 to rotate. The rotation of the rotating shaft 13 causes the eccentric wheel 14 to rotate, which in turn causes the moving plate 15 to move. The movement of the moving plate 15 causes the connecting rod 12 to move, which in turn causes one or two piston plates 11 to move. The cooling chamber 6 contains a certain amount of coolant. First, one of the piston plates 11 pushes the coolant in the cooling water tank 9 through the inlet pipe 7 into the cooling chamber. Inside the cooling chamber 6, the coolant level increases. Excess coolant is discharged through the outlet pipe 8 into the cooling water tank 9 connected to the outlet pipe 8. The piston plate 11 inside the cooling water tank 9, under the action of the linkage rod 12, discharges the internal coolant through the connecting pipe 10 into the cooling water tank 9 connected to the inlet pipe 7, thus completing the circulation of coolant. The coolant discharged from the cooling chamber 6 carries away the heat in the charging compartment 2, preventing the continuous accumulation of heat from causing the battery to overheat and damage or explode. After being cooled in the cooling water tank 9, the discharged coolant re-enters the cooling chamber 6, realizing the recycling of resources, which is in line with the concept of green development.
[0030] After the battery in charging chamber 2 is fully charged, the telescopic cylinder moves the lifting plate 4 upward. At this time, due to the charging of the battery, some electrolyte will be discharged into the liquid collection box 3. Because the charging chamber 2 has a certain temperature, some electrolyte will evaporate into acid mist. If it is not absorbed or discharged in time, it may endanger the health of workers when they open the chemical formation cabinet 1. The rotation of the rotating shaft 13 drives the cam to rotate, the rotation of the cam drives the push plate 16 to move, the movement of the push plate 16 drives the rack plate 17 to move, the movement of the rack plate 17 drives the spur gear 18 to rotate, and the rotation of the spur gear 18 drives the bevel gear 1... The rotation of bevel gear 19 drives the rotation of stirring rod 20. The rotation of stirring rod 20 continuously agitates the dry absorbent (such as sodium hydroxide or calcium hydroxide) on the placement plate 22, allowing the dry absorbent to fully absorb this part of the acid mist, avoiding the acid mist from harming the health of workers and improving the harmlessness and safety of the device. When the dry absorbent on the placement plate 22 absorbs a certain amount of acid mist, its weight increases, and the placement plate 22 will compress the pressure spring downward. The indicator rod on the placement plate 22 will move downward accordingly, so that workers can observe the indicator rod to determine whether the dry absorbent needs to be replaced or added.
[0031] When it is necessary to remove the battery, simply pull the charging compartment 2. The charging compartment 2 slides out of the formation cabinet 1 through the slide rail 23, making it convenient for workers to remove the battery and improving work efficiency. At the same time, workers do not need to put their hands into the formation cabinet 1, ensuring the safety of workers.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
