Problems solved by technology
The existing operation method is to manually use the corresponding iron sheet to bend the tabs, which requires a large labor force and slow production efficiency; and after the battery was dissected later, it was found that the top of the AGM separator near the side negative plate in the battery cluster had penetrating damage. short circuit of the battery
After verification and analysis, when the damage is caused by artificially bent tabs, the tabs are forced to squeeze the separator, and the squeezed separator is subjected to current action during the later repeated charging and discharging process to form penetrating damage, resulting in a micro-short circuit of the battery, which greatly Reduced battery life

The invention discloses a side-inserted bent pole lug mold. The side-inserted bent pole lug mold comprises a base; an upper baffle plate is arranged above the base in parallel; the base is connected with four angles of the upper baffle plate through support columns; the base is provided with a battery limiting groove; a pressing bar return box is mounted at the middle part of the end, far from anopening, of the upper baffle plate; the pressing bar return box is provided with a pole group limiting pressing bar extending to the opening direction of an adjusting groove; cylinders are symmetrically mounted on two sides of the bottom of the upper baffle plate; output ends of the two cylinders are opposite; pole lug bending devices are mounted at outer ends of piston rods of the two cylinders;the pole lug bending devices comprise pole lug limiting insertion cutters with L-shaped structures; and plate lug bending cutters are mounted at the tops of the pole lug limiting insertion cutters. Pole lugs are bent by adopting a side inserting mode; and when the pole lugs are precisely bent, AGM separation plates are protected by using the pole leg limiting insertion cutters, so that the technical problem of micro short circuit caused by extrusion damage of the AGM separation plates can be effectively solved, and the production efficiency is greatly improved.
Description
technical field [0001] The invention relates to the field of battery production, in particular to a side-inserted bent tab mold. Background technique [0002] Lead-acid battery refers to a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main component of the positive and negative electrodes is lead sulfate. Divided into vented batteries and maintenance-free lead-acid batteries. The most obvious feature of a lead-acid battery is that it has a twist-off plastic seal on the top with ventilation holes. These filling caps are used to fill pure water, check electrolyte and discharge gas. With the upgrading of battery manufacturing technology, lead-acid batteries have developed into lead-acid maintenance-free batteries and colloid maintenance-fre...
