18650 lithium-ion battery double-sided automatic spot welding machine

The 18650 lithium-ion battery double-sided automatic spot welding machine is an automated equipment specially used for welding the positive and negative electrodes of 18650 lithium-ion batteries at the same time. The following is its relevant information:

How it works:

Welding is carried out using the resistance heat generated by passing electric current through the welding points of the workpiece. During operation, two electrodes squeeze the workpiece, causing the two layers of metal to form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, an instantaneous thermal welding is formed at the two contact resistance points. The welding current flows from the other electrode along the two workpieces instantaneously, forming a loop without damaging the internal structure of the workpiece to be welded.

Equipment features:

Efficiency: It can complete multiple spot weldings in a short time, significantly improving production efficiency. According to different splicing modes, spot welding efficiency can reach a high level to meet the needs of mass production.

High accuracy: Adopt advanced control system to ensure accurate spot welding position, avoid welding deviation and ensure battery quality. Supports various packaging forms of welding, giving the battery a longer life and higher durability.

High degree of automation: realizing automatic feeding, automatic welding, automatic unloading and other functions, reducing manual intervention, reducing production costs, and improving the overall automation level of the production line.

Strong adaptability: It can support any series and parallel combination of up to multiple 18650 cells, as well as different specifications and special packaging forms. At the same time, the welding parameters can be flexibly adjusted to meet the production needs of batteries of different specifications.

Good stability: Using high-quality materials and advanced production technology to ensure the stability and reliability of the equipment, and having a complete after-sales service system.

Technical parameters:

Spot welding speed: For example, the spot welding speed of some equipment can reach more than 3,600 cells per hour.

Stroke range: Generally speaking, the Y-axis and Z-axis strokes of the equipment will vary according to the specific design. The common Y-axis stroke is above 600mm, and the Z-axis stroke is above 320mm.

Air pressure requirements: Usually the air pressure of the equipment is 0.4~0.7MPa.

Parameter storage: Multiple sets of files can be stored to facilitate calling different welding programs and parameters.

Application fields: widely used in electric vehicles, smartphones, energy storage systems, power tools, twist bikes, electric bicycles, solar street light battery packs, etc.
