Description

Technical Field

[0001] This invention relates to the field of battery busbar welding technology, and more specifically, to a welding process for battery busbars. Background Technology

[0002] In today's era of rapid technological development, batteries, as an important energy storage and conversion device, play an indispensable role in many fields, from the power source of electric vehicles to the power supply unit of portable electronic devices, and to the application of large-scale energy storage systems. The performance and reliability of batteries directly affect the operation of the entire system.

[0003] Among them, the battery busbar, as a key component connecting individual battery cells, modules or battery packs, undertakes the important task of current transmission and distribution. However, the quality of the battery busbar welding directly affects the electrical performance, thermal management performance and overall safety of the battery. Good welding process can effectively reduce connection resistance, reduce energy loss, improve battery charging and discharging efficiency, and at the same time ensure the stability and reliability of the battery pack during long-term use.

[0004] Currently, common welding processes for battery busbars include resistance welding and ultrasonic welding. While resistance welding has the advantages of simple equipment and convenient operation, it achieves welding by generating resistance heat at the contact point of the workpieces through current. This results in problems such as unstable weld joint quality, easy spatter, or busbar deformation. Ultrasonic welding, on the other hand, uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, they rub against each other to form a fusion between molecular layers. Although this process is fast and produces high weld strength, the equipment cost is high, and it has strict requirements for the cleanliness and flatness of the workpiece surfaces. Furthermore, the high-frequency vibration generated during the welding process may cause misalignment or incomplete welding of the internal structure of the battery or the weld joint of the busbar, thus affecting the welding quality of the busbar.

[0056] The working principle and beneficial effects of this invention are as follows:

[0057] 1. In this invention, when welding the battery busbar, the feeding motor is started, and the output end of the feeding motor drives the feeding screw to rotate. The rotation of the feeding screw drives the feeding ball nut assembly to move, the movement of the feeding ball nut assembly drives the feeding slider to move, the movement of the feeding slider drives the feeding adjustment frame to move, the movement of the feeding adjustment frame drives the welding component carrier frame to move, and the movement of the welding component carrier frame drives the feeding sealing plate to move to one side of the welding box. Then, the assembled battery busbar is placed on the welding component carrier plate. According to the position of the busbar in the battery busbar, the fixing bolts are loosened. By adjusting the position of the height adjustment frame, the frame positioning plate moves to one side of the busbar. By pulling the adjustment plate, the adjustment spring and adjustment slide rod move. Under the rebound pressure of the adjustment spring, the box positioning plate and the frame positioning plate fix the bottom box and the top busbar of the battery busbar, thereby fixing the battery busbar.

[0058] 2. In this invention, after the battery busbar is fixed, the feeding motor is started to move the welding component carrier into the welding box, so that the feeding sealing plate contacts the feeding through hole. Then, the position of the welding point on the busbar and the laser welding head assembly is monitored by the welding monitoring camera. By starting the X-axis adjustment assembly and the adjustment motor in the Y-axis adjustment assembly, the output end of the adjustment motor drives the adjustment ball nut assembly to move. The movement of the adjustment ball nut assembly drives the adjustment slider to move. Under the movement of the adjustment slider, the welding plate and the laser detection camera move. At the same time, by starting the Z-axis adjustment cylinder, the welding plate and the laser detection camera move to any position above the battery busbar under the movement of the output end of the Z-axis adjustment cylinder. By starting the mechanical welding head assembly, the welding point on the battery busbar can be laser welded.

[0059] 3. In this invention, when laser welding the battery busbar, a fume extraction fan is activated. The fume extraction fan blows outside air through the cooling pipe onto the spot-welded part of the battery busbar. The airflow not only cools the weld point quickly, but also discharges the fumes through the fume extraction pipe. By installing a fume extraction device at the fume extraction pipe, the fumes can be treated. Attached Figure Description
