technical field

The invention belongs to the technical field of electrolyte injection and absorption, in particular to a centrifugal absorption device for alkaline dry battery electrolyte.

Background technique

Alkaline dry battery is a long-life disposable battery, which is improved on the basis of common zinc-manganese acid batteries. Also known as alkaline manganese dry battery. The shape and size are the same as ordinary manganese batteries. Due to the improved performance, it is often used as a flash power supply; during the production process of alkaline dry batteries, it is necessary to inject electrolyte into the battery. Electrolyte is an important part of the battery. The negative electrodes play the role of conducting electrons, which is the guarantee for the battery to obtain the advantages of high voltage and high specific energy.

At present, when the electrolyte is injected into the interior of alkaline dry batteries, in order to ensure that the electrolyte can be absorbed into the positive electrode ring of the battery and the inside of the separator paper, the battery is usually vacuumed before injecting the electrolyte. The vacuum environment is conducive to the absorption of the electrolyte. , and avoid air in the battery so that the electrolyte dries up and affects the subsequent service life of the battery. After the electrolyte is injected into the battery, centrifugation is often used to promote the rapid absorption of the electrolyte; in a battery injection cup with the patent number CN 105514340 B, A liquid injection cup with strong sealing is disclosed, so as to ensure that air is not mixed into the electrolyte during the liquid injection process, and at the same time, the residual amount of electrolyte is reduced by creating a negative pressure environment in the liquid injection cup, but this technology The scheme cannot effectively control the amount of electrolyte injection during use. At the same time, in order to ensure good sealing during liquid injection, the liquid injection head is tightly against the position of the battery liquid injection port. Excessive pressure may cause damage to the battery surface. If it is too small, it may cause electrolyte leakage, and its operation steps are too cumbersome, resulting in a slow injection speed.

The existing alkaline dry battery electrolyte centrifugal absorption device cannot inject different amounts of electrolyte according to the specifications of different batteries when injecting electrolyte into the battery, that is, the injection amount of electrolyte cannot be accurately controlled. In order to ensure the tightness of the battery and cause the battery to be greatly squeezed and easily damaged during vacuuming, we propose a centrifugal absorption device for alkaline dry battery electrolyte.

The present invention has the following beneficial effects:

1. The present invention achieves the purpose of accurately controlling the amount of electrolyte injection by setting the upper liquid injection cylinder and the lower liquid injection cylinder connected by the first spring, and by controlling the internal volume between the upper liquid injection cylinder and the lower liquid injection cylinder , before injecting liquid, press the bottom plate of the lower liquid injection cylinder against the surface of the battery tightly, so that a sealed environment is formed between the battery and the upper and lower liquid injection cylinders. At this time, the electromagnet is in the energized state, and the upper liquid injection cylinder moves downward When adjusting the volume between the upper and lower liquid injection cylinders, the lower liquid injection cylinder is fixed because the connecting rod is in a fixed state. Observe the number of limit blocks on the outer connecting rod surface of the upper liquid injection cylinder when the upper liquid injection cylinder slides down. By observing the number of limit blocks, we can clearly understand the internal volume of the upper and lower liquid injection cylinders at this time. After adjusting to the preset value of the battery volume, the electromagnet is powered off, and the limit blocks expand to resist the direction of the first spring. The lower pressure liquid injection cylinder and the connecting rod can ensure that the pressure on the liquid injection cylinder will not be completely squeezed on the surface of the battery, thereby reducing the pressure on the battery when it is sealed and preventing the battery from being damaged due to excessive pressure. damage; at the same time, due to the fixing of the limit block between the upper and lower liquid injection cylinders, the internal volume will not change. The inside of the upper and lower liquid injection cylinders will be filled with electrolyte, and all the electrolyte in the upper and lower liquid injection cylinders is the amount of electrolyte that the battery needs to fill. This will not cause waste of electrolyte, and at the same time can accurately control the electrolyte Refill amount.

2. After the present invention completely evacuates the upper and lower liquid injection cylinders and the inside of the battery through the vacuum pumping component, the lower liquid injection cylinder will rise upwards after continuing to pump air, so that you can know that the inside of the battery has been completely evacuated, and stop vacuuming at this time That is, since the lower liquid injection cylinder and the upper liquid injection cylinder are connected by the first spring, the first spring will prevent the lower liquid injection cylinder that has not been evacuated from rising upwards. When the vacuum is exhausted, the lower liquid injection cylinder will It will rise, which can greatly reduce the problem of vacuuming and causing the battery to be damaged due to pressure.

3. In the vacuuming process of the present invention, the upper and lower liquid injection cylinders are first connected with the inside of the battery. After vacuuming, the space between the lower liquid injection cylinder and the battery is cut off. The second valve, due to the pressure difference, the electrolyte inside the infusion tube is pumped into the upper and lower filling cylinders until it is full. After closing the second valve, open the partition with the battery. Because the electrolyte inside the battery is not easy to fill, Therefore, the internal space of the battery is larger than the internal space of the upper and lower liquid injection cylinders. Under the pressure of the large surface area, the electrolyte in the upper and lower liquid injection cylinders quickly enters the interior of the battery, and there will be no electrolyte residue inside the upper and lower liquid injection cylinders, thus ensuring The accuracy of the electrolyte injection is ensured. At the same time, the electrolyte does not come into contact with the air during the overall injection process, and the air is not injected into the battery with the electrolyte, and the remaining space inside the battery is still in a vacuum state. The liquid will not dry up in contact with the air, which improves the service life of the battery.

4. In the present invention, a connecting rod fixed to the lower injection cylinder is provided, and an electromagnet is arranged inside the connecting rod. When the electromagnet is energized, it is mutually adsorbed with the magnetic suction ring, so that the connecting rod is fixed. At this time, the upper and lower injection liquid is adjusted. The size of the volume between the cylinders will not cause excessive pressure on the battery connected to the bottom. After the adjustment is completed, when the electromagnet is powered off, the connecting rod slides downward and is blocked by the expanded limit block, so that most of the load on the connecting rod comes from the bottom. The falling force of the liquid injection cylinder, a small part of the force is borne by the battery to play a sealing role, avoiding the electrolyte splashing when the battery is centrifugally rotated; at the same time, the limit blocks arrayed on the surface of the connecting rod from top to bottom not only play the role of fixing the connecting rod , it also has an intuitive display for understanding the internal volume of the upper and lower filling cylinders.
