Description

Technical Field

[0001] The present invention relates to the field of battery processing equipment components, and more particularly to a lead-acid battery casting and welding machine and its casting and welding method. Background Art

[0002] A casting and welding machine, also known as a fully automatic battery casting and welding machine, is a casting and welding device for small valve-regulated sealed lead-acid batteries. The whole set of equipment includes a fixture, a mold, a melting furnace, a cooling device, and a demolding and inserting into the battery case device.

[0003] The lead-acid battery for electric scooters consists of important components such as a plastic case (usually made of ABS or PP materials), a plate group (composed of positive plates, negative plates, bus bars, and separators), and bus bars. The tabs and the bus bars are formed by casting and welding. The tabs are connected by the bus bars at the upper part, and there is no bus bar at the bottom. When the battery is in use, the current passes through the positive connection part and then through the negative connection part to obtain the current. However, the battery with this structure has low utilization rate, relatively high cost, and short cycle life. To improve the battery life, it is necessary to improve the plate group structure of the battery. For the improved plate group structure of the lead-acid battery, when using a casting and welding machine for the casting and welding process, the requirements for the casting and welding machine are relatively high. Therefore, there is an urgent need for a lead-acid battery casting and welding machine that can meet the casting and welding requirements for improving the plate group structure of the battery. Summary of the Invention

The inserting into slot drive mechanism is arranged below the lifting drive mechanism and is used to move the battery plate group. The flipping mechanism is arranged on one side of the inserting into slot drive mechanism and is used to flip the battery plate group. The thimble drive mechanism is arranged on the other side of the inserting into slot drive mechanism and is used to clamp the battery plate group.

The plate group is installed in a battery case, and a plastic case separator is provided between adjacent single groups of plate groups to fix and support the plate group structure. The lifting drive mechanism drives the soldering die to move towards the lead pot, heating the soldering die in the lead pot. After the temperature reaches the process design requirements, the lifting drive mechanism drives the soldering die to lift upwards to a set position. The slot-in drive mechanism drives the battery plate group to move towards the lead pot direction, pushing the battery plate group into the soldering die to complete soldering. The lifting drive mechanism drives the soldering die to move towards the lead pot again, heating the soldering die in the lead pot for secondary temperature rise.
