Control device for automatic and quantitative paste feeding to lead storage battery coating plate

Abstract

The invention discloses a control device for automatic and quantitative paste feeding to a lead storage battery coating plate. The control device comprises a photoelectric sensor, a switching power supply, a first intermediate relay, a time relay, a second intermediate relay and a paste feeding motor. The photoelectric sensor, the switching power supply, the first intermediate relay, the time relay, the second intermediate relay and the paste feeding motor are connected in sequence. A breaker is connected between the photoelectric sensor and the switching power supply. A switch is connected between the second intermediate relay and the paste feeding motor. The control device controls the paste feeding motor to add lead paste continuously, quantitatively and uniformly through the photoelectric sensor, the switching power supply, the intermediate relays and the time relay, arbitrariness and non-quantization of paste feeding are avoided, the influences imposed by inconsistent pressure of the lead paste in a paste hopper on paste feeding can be eliminated fundamentally, the weight and thickness uniformity of a polar plate is greatly improved, and the service life of a battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of production and processing of lead-acid batteries, in particular to a control device for automatically quantitatively applying paste to coated plates of lead-acid batteries. Background technique [0002] Valve-regulated lead-acid batteries are composed of main parts such as battery plastic case, positive and negative plates, separators, electrolyte and terminal poles. The addition of lead paste in traditional coating production is controlled by the operator. There are great uncertainties in the amount of paste applied and the timing of the paste hopper of the plate coating machine. The difference in the pressure caused by the lower paste port of the plate coating machine is inconsistent, and finally causes the difference in the paste output of the plate coater at the same frequency of paste application, resulting in a large difference in the weight and thickness of the positive and negative plates. In the...

Problems solved by technology

In use, the existing method is to match the heavy plate and the light plate in the same single-cell cluster to keep the weight of the living matter in the single-cell cluster consistent. Since the plates are used in parallel, in the same discharge and charge process , causing the plate with more active matter to be in a state of depletion when replenishing electricity, and the plate with less active matter to discharge is in an over-discharge state. Long-term cycle use will cause premature passivation of the electrode and end its life.

Due to the inconsistent thickness of the plates, there is also a difference in the assembly pressure of a single battery cluster. If the assembly pressure is too tight, the acid content of the plate is insufficient, resulting in the battery capacity not being released, and the plate is prematurely damaged due to lack of acid; the assembly pressure is too loose, and the plate The charge receiving capacity is reduced, and the living matter and the grid are easy to fall off, resulting in shortened battery life
